    The Trophy 4 engine (sometimes called the Indy 4 engine) is probably the most unique engine Pontiac every developed. Things started back in 1958 when GM was reacting to the rising popularity of imports and it was feeling the effects of the ’58 recession, GM started to develop its own version of a compact cars, starting with the Chevrolet Corvair, with its rear-engine air-cooled flat six engine. Buick, Olds, and Pontiac could have replicated the Corvair but instead chose to go their own way. The ’61 Buick Special and Olds F-85 got a new V6 (which would eventually evolve in the 3800) and a small 215 cu in aluminum V8 – both engines came from Buick. John DeLorean chose to take Pontiac in a different direction and build its own economic engine. The result was a revolutionary approach: a transaxle--adapted from the Corvair--mounted at the rear for good weight distribution, connected to a four-cylinder engine through a flexible steel driveshaft (often called the “rope driveshaft”). DeLorean wanted an inline four for the ‘61 Tempest. The only problem was that Pontiac did not have a 4-cylinder engine in its inventory, and not enough money in the budget to develop a new one from scratch. But it did have its celebrated, 389-cu.in. V-8. Could it be split to make a workable four? In 1959, Pontiac had increased it’s V8’s stroke to 3.75 in, thus raising engine displacement to 388.9 cu in. This was the beginning of factory supplied performance items such as 4 bolt main bearings and windage trays to reduce friction from crankcase oil. The 389 would remain the standard Pontiac V8 engine through 1966. The 389 came in a wide variety of configurations that ranged from 215 to 368 horsepower. The 389 was the standard engine for the Pontiac GTO from 1964 to 1966. Beginning in 1961 the Pontiac V8 389 (and 421) was dubbed the Trophy V8, due to its many victories in racing after just two years. Since the 389 was called the Trophy V8, the new 4-cylinder engine was called the Trophy 4 by extension. In some racing corners, it was called the Indy 4. The Trophy 4 was a 45-degree inclined 194.4 cu inline 4-cylinder engine created from the right bank of the 389. With an identical bore and stroke of 4 1⁄16 in and 3 3⁄4 in, it was precisely half the displacement of the 389. Initial tests were encouraging. A Pontiac V8 with one bank of cylinders disabled was found to be capable of pushing a full-sized Pontiac over 90 miles per hour, with acceptable fuel economy for the day. By using the 389 as the basis for the 4-cylinder, the costs of preparing the four cylinder engine for production were significantly smaller--it shared its pistons, rings, connecting rods and more with the 389, and it even used the same tooling for its cast-iron block, thanks to shared dimensions. The crankshaft, camshaft, oil pan, intake, and other parts were unique to the four cylinder. The engine was offered in three horsepower ratings: 115hp, with 8.6:1 compression and a two-barrel carburetor 140hp, with 10.25:1 compression and a two-barrel 166hp, with 10.25:1 compression and a four-barrel The Trophy 4 was not an ideal compromise or design, by any stretch of the imagination. It retained about two-thirds of the mass of the 389, tipping the scales at a quoted 557 pounds, or 200 pounds more than the optional Buick 215-cu.in. aluminum V8. And its large displacement—194.4 cubic inches, made it prone to significant vibration. There was little the engineers could do about the weight and only so much they could do about the shaking. A downside of the engine’s design and configuration was engine vibration. An inline four-cylinder engine suffers from inherent secondary imbalance resulting from its 180-degree crankshaft. In its design, the two outside cylinders move together simultaneously, as do the two inside cylinders. Due to geometry and the ignition cycle, a piston descending from top dead center will always move quicker through the first 30 degrees of crankshaft travel than a piston moving upward from bottom dead center, meaning that more mass is moving downward than is moving upward, causing a shaking in the vertical plane. Today, engineers consider the installation of twin counter-rotating balance shafts a necessity for engines larger than 122 cu in (2.0 L). The V8-based design of the Trophy 4 lacked balance shafts due to cost (note - balance shafts didn't get popular at GM until the late 1980s/early 1990s). It was instead cushioned by a flexible rubber engine mounts designed to isolate the engine from the rest of the car, and its forces were further dampened by the Tempest's unusual drivetrain (which distributed forces by the engine being bolted directly to a rear-mounted transaxle via the solid outer tube of its driveshaft. The timing chain in the Trophy 4 was originally the same as the 389’s but was prone to stretching and breaking from the inherent engine vibration; therefore a special high-strength version was developed as a replacement. What killed the Trophy 4 was not its tendency to shake, or its habit of snapping timing chains, instead it was Pontiac's decision to move away from the transaxle design when the Tempest was re-designed from a compact to an intermediate for 1964. The slant-four was dropped as the base engine, replaced by the 215-cu.in. straight-six overhead valve engine from Chevrolet (this Chevy straight six lead directly to the development of Pontiac's OHC 6 engine in 1967). Today, the Trophy 4 can be made to produce 300hp in normally aspirated form, and more than 500hp with either a turbocharger or supercharger, if balanced and built with modern parts and techniques. These motors are much smoother than new too. They are very strong engines that weigh about the same as a small block Chevy",according to Ken Freeman, owner of East West Auto Parts in Tulsa, Oklahoma. https://books.google.com/books?id=0tsDAAAAMBAJ&pg=PA4&lpg=PA4&dq=pontiac+"trophy+4"&source=bl&ots=in8hgEZRl9&sig=Ya4PU_4exyy5QmhqctXM3-qnf4o&hl=en&sa=X&ved=0ahUKEwjC-aat95vZAhUJbK0KHXYzAHY4FBDoAQguMAI#v=onepage&q=pontiac "trophy 4"&f=false http://autoweek.com/article/car-life/cut-down-engine-week-pontiac-trophy-4 \ Cut Away of the 194 The 194 in a stock Tempest Blown Trophy 4 4-barrel intake manifold

    I'm in Chandler AZ visiting my daughter, son-in-law, and grandsons. This past weekend (2/24-2/25) my son-in-law, one of my grandsons, and myself, went to qualifying and finals of the NHRA Arizona Nationals at Wild Horse Pass Motorsports Park. We had awesome seats both days at the start line. Here are the pictures I took, in no particular order, except that the first four are Pontiacs- a '67 Firbird, a '70 Formula, and two pics of a Grand Am Pro Mod. There were a couple of late model GTOs, but the pictures were horrible. The lack of Pontiacs was sad. There is a picture (#7) of John Force (Peak) and Jonnie Lindberg (Head) as they are inching forward to break the staging lights. This is the race where John Force's engine blew up and he crashed into Lindberg. Hope you enjoy the slide show... http://s931.photobucket.com/user/us_strat/slideshow/AZ NATS?sort=4

    First pic is what she looked like to start. Interior was shot and needed a 100% redo. The last pic is the motor after its rebuild. It is a start. The metal work is all done on the body and it will be in primer soon. Frame is ready for the motor now. Brakes and all gas lines run. Making progress.

    IMO, this engine was an exercise in design. It was conceived at a time with no real market, it just seems someone said what if or wounder if and they decided to give it a go. More of a lets see if we can exercise. I like them due to this odd ball factor but I also have collected and built several OHC's ... enough said

    Not much progress lately. Got some quotes for seat upholstery and while I was out threw the alternator belt. Then I took the seat and carpet out, I found a hole through the floor. I crawled underneath to see the hole from underneath and also found a core plug or freeze plug leaking. I also noticed someone had wired a piece of 2x4 to a crossmember but couldnt figure out why exactly. So Ill be patching the hole in the floor pan, spraying rust converter everywhere and installing some carpet when my order arrives.

    Hello all! I am new to the site but with an old rare car. I have a 71 GT37 that is in the process of a complete frame off restoration. It is a pain staking process I now know but it will be worth it when it is done. Did a little build on the 350 motor. Added a Ram AIR III cam and bored it to .30 over. Installed a 4 barrel Rochester and a Edelbrock intake. Wasn't looking to make a monster out of it but a nice sounding muscle car. Interior will be 100% redone. Have all the parts just looking to get the body in paint first.

    True enough. The real test, of course, is if it can pull the trailer right out from underneath the boat. Then you've got something with some get up and go. Even the knuckleheads on "Roadkill" haven't accomplished that one yet.

    Somebody just blew the biggest "trust me" in the auto industry today. The implications are staggering. Can you imagine flawed autonomous vehicles randomly hitting and/or killing people nearly every day? Would this be acceptable to society? I doubt it. Who would the NRA-equivalent scapegoat be in this case? The automobile companies, the software/sensor developers, or companies, like Uber, that run and manage the fleet? This is the biggest argument against autonomous vehicles. Not saying that people-driven vehicles don't kill people, but there is an understood perception of who's in control.

    Thank you Last Indian, thank you Ringo ! It's good to get presents !!! We celebrated my birthday early yesterday with Jacob and my in-laws since the kid was still home on spring break. He had to leave shortly after dinner to head back to college. So I've got a new GMC and a new Pontiac baseball hat A new black Pontiac T-shirt and a very cool red Pontiac sweatshirt. I also got the book GMC The First 100 Years by John Gunnell. I also got some wireless headphones and a HALO Bolt AC/DC Portable Charger & Car Jumper - its a multi-purpose battery pack/charger. I can charge a laptop, tablets, cell phones, or even jump start my car with it. I also got a couple of music CDs I wanted from Styx and Mike Love (of the Beach Boys). http://www.qvc.com/HALO-Bolt-ACDC-PortableCharger-%26-Car-Jumper-with-AC-Outlet-%26-Car-Charger.product.E230549.html?sc=NAVLIST Tonight the wife and I are going out to Red Robin for dinner - free birthday dinner, you know. I love the Royal Red Robin burger! This weekend, my wife is heading out of town for a long weekend of scrap booking with her sister, so my dad and I will got out for a steak dinner.

    Thanks stratman. A few years before John Sawruk passed away, the Michigan Widetrackers asked him to select a car for "Best Engineered" car at their annual Spring Dustoff car show,. Ater all John was a certified professional engineer (P.E.). John picked a red '63 Tempest convertible with the Indy 4 and the original rope driveshaft. John said he selected it because it was the only car at the show with this unique drivertrain combination. No other Pontiac ever had something like this - before or since.

    Excellent and thorough article , Frosry! The "Indy 4" is indeed a forgotten engine, thanks for the reminder. When I was a kid, my older brother (by seven years) had a '62 Tempest with the 4 cylinder. That's all I remember about it, because he had an Austin Healey 3000 before the Tempest and I couldn't believe he got rid of the really cool Healey and got this (in my 12 year old kid's opinion, lol) 4 cylinder grandma car...This was the first Pontiac in the family and I was not impressed! The Healey of course, being British, required constant "tinkering", and I think my brother got sick and tired of it and just wanted something that was cheap, reliable transportation as he was in college at Virginia Tech. Alas... no more being the cool kid riding around in an Austin Healy, lol! Here's Mickey Thompson's Indy 4 racers... http://www.tachrev.com/NHRA_Museumpg4.htm

    Well maybe things have changed, so you will have to do some investigating, but hands down the best headlights I ever ran we’re in my 69 Z. They were 7” round aftermarket Cibie headlights that were direct factory replacements. They were not sealed beams and they took an H4 bulb. I run HIDs in my Lacrosse’s and my Grand Prix and they still don’t come close to the Cibies. The Cibies I ran had used 24 percent lead crystal lens, a true mirror plating on the back metal reflector parabolic. The actual performance came from the lens. While it was a 7” round light the lens threw the light down and slightly to the right no light existed above the horizon mid line. Just like a projection headlight in today’s cars, but without any loss due the thick magnifying lens and a multiple bounced light signal that has loss due to opacity issues.

    This is my 1994 25th Anniversary Trans Am GT. There was only 2,000 produced and this is 1 of only 91 with all the factory options including a HURST 6-Speed Manual.. It has 19,750 miles in original showroom condition. These models also had the honor of being the Pace Car for the 35th Daytona 500.

    IT is a great pleasure to be a "newbie" on this site as I am a long-time Pontiac enthusiast! My first ownership began back in 1976 when as a High School Senior, I purchased a '64 LeMans from my neighbors. Not a GTO by any means (flat 6, standard brakes), it still started me on my Pontiac journey- which included: 1984 T-1000, 1986 Sunbird, 1988 Firebird (V6), 1996 Grand Prix GT, 2004 GTO (my buddy Mike and I were early adopters of the Monaro/GTO and Pontiac Performance Magazine actually did a photo story on us called "Blood Brothers" as we lived several houses apart), current ride: 2002 Firebird. Sunset Orange Metallic. Apparently, it was one of the last couple of hundred produced and I thoroughly enjoy it! Although I drive a german performance sedan during the work week, I intend to keep my 'Bird for a long long long time! I never had a car with T-tops before this one and I love opening it up and cruising alongside the beach on FL A-1-A, going to the local "Cars & Coffee" once a month.

    Thanks! I should mention too that my dad had his share of Pontiacs back in the day (although he was definitely more of a Buick guy)- he had a '60 Catalina, a '70 LeMans (which was commandeered by my brother as it had that nice 5.7 L V8), and an '02 G6. At any rate, I've always dug PMV more than any other division; I still have a good number of original brochures from the dealerships. -Scottie

    Wow! That's some good stuff he's smoking right there. I wonder if I can afford to buy any of it....or at least inhale it. I won't debate the advantages of diesel engines over gasoline engines. However America and most of North America has endured the Oldsmobile diesel quality issues of the late '70s/early '0s and the VW diesel emissions scandal, which has effectively killed demand for diesels in passenger cars for most of North America. So diesels are tough sell here and will continue to be for a long time to come. Diesels in pickup trucks have tons of advantages with none of stigma.

    How fast do you want to go? What are your goals and budget for the car? It sounds like you are trying to stay close to stock based on the fact that you are using 500 cfm Holly 2-barrel rather than upgrading to a 4-bbl intake and carburetor. The cam specs you've chosen are close to stock 268 degrees intake duration with .420 intake / .442 exhaust lift. Is that at 1.50:1 or 1.65:1 lift? The stock Rochester 2-bbl carbs run around 250-280 cfm, so you've clearly added the potential for more air with the bigger Holley carb. I think you could break 100 mph in the quarter but that means you really have to dial in the carb to the cam. Too much air and leaning out the fuel mixture too much won't help you get down the track - the proper jetting is key here. Get all your mechanical and vacuum advance in as soon as possible too. The 1973 motors were not considered horsepower monsters by any stretch of the imagination. GM had switched to net HP/torque ratings (meaning that engines were rated with all parasitic drag elements in place like A/C and power steering pumps, alternators, and air cleaners and filters in place. Previously, GM used gross HP/torque figures which removed all these items. In 1973, a 2-bbl 400 could expect to make 170-185 HP (at the flywheel), while a 4-bbl 400 would be rated around 200-230 HP. So don't expect any huge numbers at the rear wheels. Also, these cars were coming into the era of (then) new unleaded fuel and emissions. So compression ratios also started coming down to handle the lack of lead (which helped manage engine knock or detonation in those days), which further helped reduced HP figures.

    It was a custom made Vega body & it was about 1/2 scale! Look at #80 in the attached link. This was one of his fastest times I knew of, 3.225 sec. 1/4 mile @ 392 mph, but he traveled the country with the car, I wasn’t involved in that. Basically the car would go as fast as you wanted it to go! I’ll explain. Nagel was a smart guy, you have to apply for a federal license to use hydrogen/rocket fuel. While the principal is simple, it’s very dangerous, the Challenge explosion! All the other cars you see that say rocket, aren’t they’re jet engines! Even the pocket rocket of Nagel’s that’s been resurrected is now a jet engine. A rocket engine in very simple principle is push hydrogen through a platinum screen and you produce thrust. The larger the volume and the fast the flow through the screen the more thrust. The real issue for him was stopping! Some track have pretty short run after the finish. http://www.draglist.com/draglist/category.php?VIEW=Extended&CATEGORY[0]=ROCKET&x=exhibition&SORTBY=ET%2CYEAR%2CMPH+DESC&page=3

    Just to clarify, when I said we raced together at a couple tracks I didn’t mean to imply I raced him or even Funny cars. I was a bracket racer, but at that time I was helping a guy Larry Nagel with a car called the Pocket Rocket. It was in the development stages then. It ultimately had a rocket engine in it, yes Hydrogen! Anyway even then, Force was impressive. The Rocket has recently been resurrected! It is a tiny car as you can see!

    The tachs are far from perfectly sealed up so the heat buildup in the tach evaporates the moisture in the case and the positive pressure moves it out of the "leaky" case. The front glass has no sealer around it and is where most of the moisture comes into the case. Mine usually only fogs after washing the car and then driving the car. It dries out fairly quickly.
