    I love your goal too. I love putting rice rockets back in the bowl.  Since this is primarily a street car and part time race car, you have to be able to live with it on the street.

    Indyman Joe's car is a good example. He has a stout 400 under the hood of his '72 Luxury Lemans. It's strong. He does the occasional 1/4 mile just to beat his buddy's big dollar Camaro. However, Joe's car is still a street car that he can take cruising or on long weekend and Sunday drives with his wife. It has no roll cage, stock interior, no line lock, but it does have a Ford 9" rear end and 4-wheel disc brakes (now). Someday he may actually paint it (sorry Joe - you know I had to kid you about it!). 

    True, true! My “69” Z was that car! As a new car it was a great all around car! Quick, fast and semi comfortable for a sports car. Yet over the 35 years of ownership I did end up going to far from a comfort perspective, or at least so my wife said. 😞 

    A 600hp mid 10 second car that pulled 1 & a quarter Gs on a 300 ft skid pad wasn’t that great for the street except for short durations. 3800 rpm @ 55mph 6 mpg. A fairly stock exhaust that you could hear coming due to the rumble 2 blocks away. All  were part of the reason I sold it after 35 years of ownership!

    Hitting those Rice rockets is my pastime but i want to make sure i can embarrass them with a Naturally Aspirated Motor. So in a sense, i will be racing with the engine. not every day, but i will be frequent enough to the point where i want to be able to drive the car home from the track every race. And i've already gotten the new Posi rear, 3.75 gear, rear disc brake conversion, suspension and all the other goodies. It's just a matter of getting the parts on since she's undergoing some SERIOUS metal work on the floors and rails. 

    Super friggen useful to know. might be why the Girdle comes with studs and nuts too. But i think i'll be taking the Girdle route as it's more Peace Of Mind.

    Nothing wrong with that!!

  3. As a side bar, a couple of things you can do to improve 2 bolt main performance is this. Replace the bolts with studs! The proper studs will be stronger & the corresponding nuts will be stronger. Also use permatex aviation form a gasket on the stud threads on insertion of the stud. It is at this time you should torque the studs independent of the caps. Then when you install the caps over the studs apply this same permatex to the top threads, install the nut and torque the cap.

    No photos this time, unfortunately but i took my entire engine apart and took a good look at the bearings. Apparently i was leaking oil out of the oil pan faster than i could keep up so i need new bearings, which is no big deal. I already have an aluminum oil pan, black and silver finned ready to install. HOWEVER i need some mucho geniuses here.

    I have the 2 bolt main Block. Not very strong, safe zone is up to 500hp and i understand this. The current engine components already make up to 420hp with a stock specification crank shaft. I've recently found that there is a Main Girdle i can use which essentially makes the block a 10 bolt main by connecting all bearings, increasing its strength and reliability to pump out more than 500hp. Great right? Now, since that's an option, would it be okay to throw in a stroker crank and make this into a 383 stroker? or would doing this be too risky?

    Well actually a 2 bolt main can handle 600 hp & 7000 rpm, but there is a lot that goes with that statement! If you’re talking racing? Than no! If you’re talking street once in a while then yes. Main cap flex in a 2 bolt starts at just under 600 hp and about 6000 rpm. The advantage of this type of build is more low end power, if done right. The disadvantage is if you get over zealous & fuel economy. 

    So in general I would skip the girding and just do a good build.

    Heading down now to play for the day as they are calling for storms/T storms anytime 5pm and beyond.  So far claiming Saturday will hold off the rain until at least 6pm.   I can't believe it.  The county is dumping cloride  (helps keep dust down on our dirt roads)  But it is 5 times more corrosive then road salt.  They dump it so heavy it turns the road to slop.  Now I have to drive over a mile to pavement multiple times in the next 2 days.   Freakin wonderful.....

    Hope the weather holds for you guys! Terrible about the chloride, I feel for you! Why don’t they use road oil? Not that that makes any less of a mess, but at least it’s not corrosive!

    The greatest automotive car cruise week in Michigan has officially begun! 

    I hope you guys have great weather and a even better time. I thought I might make it up there to see you all this year, but that just doesn’t look like it’s in the cards, sorry!

    Wow, sounds great but suspect it is beyond my ability to do.  I did check compression in each cylinder and they are within 8 psi of each other.  I have read about hot rod engines that have to have significant vacuum pump to decrease crankcase pressure.  There are expensive electrical flow meters beyond reasonable price (more than rebuild).  Engine was rebuilt about 25,000 miles ago (1985).  Only recently started leaking problem.  I have recently replaced power brake booster and 4-wheel disc brakes.  Noting that the brakes work great but would new booster contribute to problem?  Got my license in this one family car in 1968 and have owned it since 1974.  I need to figure this out.  Thanks for your feedback.

    Ok, let’s back this up for a minute. First it is possible that you don’t have to much blow-by! If you don’t have oil depositing at the oil fill, the PCV or valve cover gaskets, but only a rear seal leak, than that doesn’t mean crank case pressure. 

    First, what was the condition of the crank journal where the seal runs? The seal could have been put in wrong or nicked. If the journal was polished for the new seal that needs done properly, otherwise that can actually induce leakage as rpms increase.

    Finally, you need to step through this step by step. First find a rubber hose that fits over the dipstick tube, connect the other end to a pressure gage. If the reading is under a pound or less the problem is the rear main.

    Do you know of a fairly inexpensive but effective device?  Guess I could block oil port in valve cover and connect to pcv grommet at intake?  Interesting that no oil accumulates at oil spout breather.

    An accurate as well as inexpensive test is a leak down test. This may be preformed in different ways, but all serve the same purpose. Put air in each cylinder with all valves closed and see how long that cylinder holds pressure. There is a tool that allows you to replace the spark plug, connect a compression gage and an air chuck. With this arrangement you bring each cylinder, one at a time, to TDC. This closes the valves for that cylinder, add 150 psi, close the air port off, read the compression gage and wait to see how long it holds pressure. This tells you what your blow-by is in each cylinder.

    Had rope seal and began leaking, then recently replaced with new 2 piece viton by instructions.  Pulled engine.  Mechanic did work. Does not leak at idle, only when increase rpm.  Suspect old seal was ok and that I have increased crankcase pressure at higher rpm than idle. Really not sure.  Considering addition of vacuum pump.  PCV works.  Appreciate info on best solution.  

    Well that’s a possibility, but easy to check! Measure the blow-by. Or dump the PCV and put in breathers on both valve covers.

    I went to my local Kroger after I got out of work last night. My wife wanted me to pick up some sandwich items. In the parking lot I see they had just finished a BBQ. 

    Yup, they were apparently serving flambe Chevrolet !





    Hey I see there is a Chevy dealership right there, maybe it was a fire sale! 😁

    Speaking of Kroger, they left Northeast Ohio about 40 years ago! Makes no sense, as the company is from Cincinnati Oh.😮 go figure?

    There is place up here called Morad Parts. https://moradpartscompany.com/ they have always been good to deal with. I see the have a couple BCMs, but what they may have that they don’t show online are wiring harnesses. You might call and talk to them. They have always been quite knowledgeable & helpful. Ed is the owner, if you can talk to him.

    So I have a GT and I'm in the process of swapping the BCM off of a GTP to get the HUD working, I hear if I disconnect the BCM I will trip safe mode... What do I need to do to swap it correctly? 

    I have never needed to do anything with my BCM, but there is a company that can most likely help answer your question. https://newrockies.com/ 

    There are a lot of things I have deleted from my GP & some have been security aspects, but not all and none have been removed off the BCM

    As a side note, the GPs did not have to be a GTP to have HUD.

  14. Kudos to you GPA! All here will certainly support your effort. An interest in car mechanics can serve you well! It can teach you more about mechanics that will span across so many genres, categories, designs and structures that it would take a book to explain it. The explosion of the industrial revolution was driven as much by the automotive industry as anything, so you go boy! 

    If you have question we’ll do our best to answer them.

    No name yet... the working name is "Junior" as in "Black Betty Jr", lol!  I'll need another week or so to discover her name.

    The engine compartment, even with that dang Chevy 305, REALLY sold me on this baby. It is super clean and tidy, and yes, there is a LOT of bling there. I don't know what upgrades may be going on internally, but externally it has an Edelbrock manifold and carb, headers, dual (guessing here haven't measured) 2.5" exhaust with "H" pipe, aftermarket alt and distributor. It has four wheel disc brakes that about put me through the windshield the first few times I used them, lol! It has flowmaster or Magnaflow mufflers and it sounds fantastic! Everything is tight... not loosey goosey like the Vette. The Vette was quicker, but Junior is no slouch and is most definitely putting out more than the paltry 150hp stock 1981 305.  

    Money, or lack thereof, was the reason the Vette had to go. I was not looking for a car, but I saw Junior in a classic car dealer lot last Sunday and that was it. I looked her over real good and could find only a few tiny very minor things. It was a fair price and I knew it would not be there long with all the interest in "Bandit" Trans Ams these days, Monday I went to the bank, Tuesday it was mine! I haggled with the dealer for a good half hour to 45 minutes, I think he knew I wasn't going to leave without Junior. He really low balled me on the Vette right out of the box, but eventually I got more out of him, not as much as I would have liked, and he came down on the price of Junior. In the end, I was ok with the deal, the difference was about $2K more than I had guessed I was going to spend.

    I can't tell you how super happy I am! So glad to have a classic Pontiac again. I have not truly fully recovered from my wife's passing three years ago, but this is the best I have felt in a REALLY long time.



    It’s really great to see you back Strat! The car looks like a great find! I love the tan interior! I have always loved the black and gold combo with a light interior, as anyone who knows me and my 69Z might guess, great choice!

    I don’t know where the 305 is with mods or hp, but if it’s petty much stock you can get it up to a good 400hp, or anywhere in between if you so desired.

    I can understand your feelings of the loss of your wife and I’m glad you are somewhat better. I’ll keep you in my prayers!

    we are all glad you’re back, that’s for sure!

    Oh yeah! The gold pinstripe like the Bandits had that you mentioned would look killer. I think they used the same 3M gold I used on the 69, it’s an 03 gold. 03 are the last two digits in the 3M number that denotes the color, the rest of the number denotes how wide the stripe, the spacing of a double stripe, etc.

    Not implying you need to do more work,  but those Pontiac letters on the rear would be waaay  coool  if they lit up like the Ol Fieros???  Already have the exhaust going on.  Justa sayin......... I wouldn't change a thing.  The exhaust made me smile, that turned to ...... What if??????  Cause I've always thought it would be sweet to have the lit up Pontiac in my rear spoiler on the Sunbird.   I used metal in the spoiler for strength when I was building it.  Messed up my chance to cut in the letters.

    Funny you should say that buddy! I looked at doing Justa that when I started this whole concept, but decided against it finally because there is no real support for that portion of the cover. Just three flimsy plastic arms/brackets that are part of the cover that attach to the impact bumper. I felt if I cut away all that material in the letters, and then cutting loose the outer corners and then reattaching them, that the area would just be very weak and floppy and might put to much load on the corner areas. Still, I may revisit it this winter. I have a couple of ideas as to how I might support and actually strengthen that area, while still being able to back light it.

    The rear end makes this kind of grinding noise when going about 5mph or in reverse. Maybe wheels barring? U-joint? Also at a speed around 35-60, has a slight shaking I’m front end. Checked front and rear suspension, no leaks but grease inserts caked in grease. Left front strut mount broken. Rack has a slight leak as well. Anyone know what this could for sure be? Or have any recommendations on what to look for? 


    3 hours ago, Frosty said:

    U-joints might be my first suspect. I would take the car to a shop and have the rear end totally inspected. 

    The front end shake could be bad tires. Inspect your tires and see if you have blemished or deformed tires. Perhaps you have broken a steel belt in one of them. I had that happen and had a horrible shake. The fact that the left front strut mount is broken means the car is seeing stress forces it was not designed to handle. Has the car been in an accident that you know of? Any street racing or drifting? How many miles are on the car?

    I would agree with Frosty about the tires & U joints. You could also have a bent rim or improperly seated rim. The grinding noise could also be brakes or a tranny gear.

    Hi guys I am trying to replace my window trim felts and running into a problem. took the door panel off and rolled the window down to get to the felt.And I tried to loosen the screw that I thought would let me lower the window more to get to the screws but would only come down maybe 1/8th more. They say it should of came of came down as it was suppose to be the screw for the window stop.I felt all around and couldn't feel any kind of stop .Anyone have any tips on where it might be or rhe best way to get the window down another 1/2 inch or so..

    Thanks Terry

    I believe at the bottom of the tracks that the window hardware runs in there is an L shaped bracket that has a piece of rubber on the foot (horizontal portion) of the L shaped bracket. That bracket has a bolt that you loosen to adjust it or remove it. 

  19. Well I’ve gotten most of of the back cover done, still a little detail work left. The PONTIAC lettering on the lower portion of the cover still has to have gold inlays.


    This is the current modified rear cover. No wheels sticking out past the rear cover fender area. The original cover is at the last picture. This shows how much the rear fenders stick out past the cover.

    Also installed the new Indian Head






    Original cover.
