  1. I was hesitant about submitting this image since the car's been down for the last year waiting on the 13:1 CR motor install. Now I'm waiting for the 700R4 to come back from RPM Transmissions. The car also now has 17" snowflakes left in gold. I'll take new photos when it's all back together and running, again.

  2. Update: Part 13 has been reedited to correct the camshaft thrust plate mistake: >https://vimeo.com/70936437 Part 15, assembly: >https://vimeo.com/71524501 Part 16 to be uploaded next week - final assembly. Part 17 crank and run is uploaded - crank it up, guys! >https://vimeo.com/71934370 Next recording at Butler Performance for a dyno session! Next video series: Building a max performance 700R4!
  3. Hey guys: There was a mistake in the last video (part 13). Can you spot it? >https://vimeo.com/68810731 >https://vimeo.com/69113336 Part 14 is online: covers checking over the assembled heads, measuring the spring height and pressure, cc'ing the heads and calculating the engine's compression ratio. Bench testing and break-in this weekend then off to the engine dyno!
  4. On the 455: 1969 #16 GTO heads prepared by Ken Keefer, AKA Pontiac Dude. Hoping for 13:1 compression. We are cc'ing the heads and will measure them tomorrow. The Pontiac is better than most people know, according to those who use them. I mean to find out just how good. 4500 rpm because of the cam design and because there is no need to rev it more than absolutely necessary. I'd rather make up the power with more boost rather than revs. Everything now is tentative, except we will build one engine and start tuning a stock one, soon. We already started to assemble the 455 (462), uploaded in parts 11 & 12: >https://vimeo.com/67915745 >https://vimeo.com/68349318 We plan to bench fire it (break it in), but no word on a dyno shop in SC, GA, or NC.
  5. Thanks Frosty! Over at 301Garage there's been some success with this motor, including an NHRA world record holder using all stock internals. So, the feeling is that for moderate power levels the block and crank are plenty strong enough. The shorter deck height shares the same bore and stroke ratio as small block ford and chevy 302s, meaning piston speeds are way down. This coupled with a 4500 rpm rev limit and the block is not all that stressed even under an occasional blast of boost. The 301T block was beefed up over the standard '77-'79 301 and featured a crank with rolled fillets. My guess is that the engine got a bad rap because most people, myself included, for many years, still had the musclecar era performance in mind. But the 301T did exactly what it was designed to do - provide spirited acceleration for passing comparable to the 400 it replaced. In an era where musclecars were cheap discards, the complexity and underachieving 301T were not taken seriously. I, myself, owned a pair of Boss 302s during the eighties and none of the later Trans Ams were considered a threat on the street, especially the 301 cars, at least not until the '89 TTA came out and blew my mind! Now, 33 years past 1980, after the Grand Nationals changed perceptions about turbocharging and modern 4s and 6s are embraced by the current generation of tuners, the environment is right to give the 301 its fair due. Like the 455, I wouldn't be surprised to find it also north of 400 hp, but stay tuned and we'll see how this story develops.
  6. >https://vimeo.com/67009628 >https://vimeo.com/67025309 Hey guys: These last two cover most of the balancing and blueprinting process to be concluded in part 10. (I can only upload 5G a week on VimeoPlus). We've started recording the assembly, so it's finally coming together. Some others have commented on Wayne opting out of using a torque plate for the honing, but with a head screwed on it, it still seems to measure dead nuts (my new machinist term). Any guesses on the flywheel hp or rwhp ? On other news, I picked up a 1980 Turbo Trans Am Indy Pace Car, for a near future build-up, that will answer the question of slow or go? What is the potential of 301's much maligned motor given high-octane and a host of aftermarket upgrades. To some a waste of time and money - to me a challenge and a chance to redeem one of the most handsome of all the Trans Ams. Stay tuned!
  7. Hey guys. Part 6 is now online: Align honing and decking the block. >https://vimeo.com/64665860 Hopefully, we'll be rockin' this summer. I'm looking forward to doing the testing sequence and all the action shots!
  8. Hey guys. Here's part 4, prepping the connecting rods: >https://vimeo.com/63287673 Once you get on there you can access the rest or merely put Pontiac 455 in the search. We're probably about half way there and I'm really excited about the build! The .030 overbore calculation cleared the way to order and receive the Ross/Butler pistons (4.181x1.495 CH flat top forged) coupled with 66 cc heads will net 12.68:1 compression! Butler strongly recommended the Comp Cams Johnson lifters, not Rhoads, so that part of the plan changed. We're making progress, as the filming schedule allows, so stay tuned and let me know if you all are learning. Thanks!
  9. The build followed a smoothed and shaved custom or street rod aesthetic. You'll also notice the side indicator lights are smoothed, as are the door handles and locks - shaved. Look closely and you'll see that even the bumper has been smoothed a bit by getting rid of the factory step. This is an old customizing tradition that emphasizes the car's lines over extraneous add-ons or decorative elements. Only the hood and decklid have been decorated and are viewable from a high angle, the hood bird in the factory tradition, the pin-up - acknowledgement of an American tradition dating before WWII. The glamour paint also alludes to the Motorama concept cars of the fifties. The result is something familiar to old school hot rodders but different applied to a more modern car. You might want to try these styling ideas in Photoshop first on one of your project cars to see if the result is a pleasing one.
  10. I mixed up a tan flesh tone that also had pearlescent in it. I can just offer that there are no fast rules - just experiment a lot to see what looks pleasing. And remember to always use a respirator when spraying automotive paints and a fresh-air respirator system when using anything with isocyanates. I think Dru still teaches a school down here in South Carolina and does Airbrush Getaways for Airbrush Action in Vegas and other places, so you might want to take a few courses to learn from the pros first hand.
  11. I used a lot of different kandy toners over a custom metallic base, so it's hard to answer that question. I guess by blending the main transparent colors you can create from a few colors a tremendous range in your palette. I just try to paint what I see.
  12. The Iwata Eclipse is my favorite airbrush, too. I remember when Dru did that painting - it really was the one that launched his career. We both got our start airbrushing T-shirts in Myrtle Beach, something I would recommend any beginner since putting in the hours under pressure makes many highly skilled artists. Not that all professional airbrush artists are great, but like anything - practice, practice, practice!
  13. Ooops! My pin-up photo was deleted above. You all can check it out on CarDomain, though. Nothing like internet censoring!
  14. I just talked to my brother, and he corrected me - he's been running e30 since the 305 tpi turned 200,000 miles - that's 160,000 miles on e30. Also, his 3.8 turbo is in the tuner's shop as I write this, so we can look forward to that as well!
  15. Hey Frosty. I'm a master airbrush artist, myself, having the privilege of learning from and working with Dru Blair when he was starting out. You'll undoubtedly appreciate the pin-up on this car's decklid. If I remember correctly, it was 3-4 base coats (KBC08) over silver sealer, then 3 coats of clear, cut, 3 more coats cut and buffed. On standard compression engines a switch to higher levels of ethanol might produce less power in a naturally aspirated application as the fuel has less energy than gasoline per unit. However, my measurements hovered around 200 rwhp with gasoline and around 173 rwhp on e85, but it did seem to produce more bottom end torque, a typical observation among users. It is my understanding that the heat of combustion is actually cooler on alcohol and have had no issues. What is noteworthy is an improved smoothness of the motor, as if a more even flame front and more complete combustion cushioned the explosions within. I've been told on numerous occasions that the converted Q-Jet runs and feels like a fuel injected car. Both my brother and I have experimented with ethanol - he has run his own blend of e30 in his '88 GTA 305 for over 100,000 miles on an engine that has never been opened with 360,000 miles! On a high-compression NA or a turbo-application, an ethanol fueled car will see an improvement, as e85 has a rating of 105 octane (that some measure as an actual 116), meaning the engine will produce more power, without any fear of detonation. My brother routinely runs e50 in his '89 TTA. Around here the local LS tuner is providing dual-fuel tunes in 7-800 hp boosted applications. Gale Banks refers to e85 as "the biggest performance fuel bargain ever on the planet." Don't take my word for it though, just try to weed through all the misinformation out there put out by the oil powers. This is nothing new as the Model T ran on ethanol and that possible energy competition was squashed during prohibition. A good source of technical articles is D-Sport magazine. Please stay tuned to the videos to see how these theories play out in a high-compression engine, which should produce more horsepower than on gasoline, given the same engine set-up.

  18. Hey all I just introduced myself in the introductions section, but just in case you missed that, here's news about my new master engine building series: Pontiac 455, Machine Shop. I've just uploaded part 2 to Vimeo. Part 1: https://vimeo.com/60051620 Part 2: https://vimeo.com/60619852 Check it out and let me know what you all think about it, how it can be improved, etc. I'll post new videos as they become completed in the weeks to come.
  19. Hey guys: New to this forum, but not to Pontiacs or restoration. Two nice cars that I own are a custom 1979 Pontiac Trans Am, painted in House of Kolor Kandy Tangerine Base Coat and a recently purchased 1981 Daytona Pace Car. The '79 is undergoing an engine rebuild to improve power and efficiency. It's a '73 455 that was last rebuilt by Steve Norwood and myself around '97. It featured 6x heads and a mild cam. For the last two years, I ran it on E85 fuel, knowing the moderate compression was less than ideal, but wanting to experiment with converting the QuadraJet. The plan now is to raise the compression with 1969 GTO #16 heads with the Crower Ram Air IV type 60919 cam with Rhoads lifters. It also will feature Crower Sportsman forged rods, Pro-Gram four-bolt main caps and possibly Ross pistons. You can follow along with the engine build at Vimeo, by searching Pontiac 455, or linking to Part 2 of my engine building series here and then going to Part 1 first: https://vimeo.com/60619852 Thanks for having me and let me know if you enjoy my videos.
