LOL
I don't want the paint too thick, it'll add weight and slow the car down. lol

Who is going to the Pure Stock Drags this year?

[threefidee]

I will be there with Ron. Bringing the 72.

[Colin W]

I would love to bring my '71 GT-37 this coming weekend (I live roughly 62 miles away), but it's not stock. It appears to be in many ways, but the 350/TH350 two barrel was recently replaced with a 455/TH400, and the stock 10 bolt was changed to with an olds, 12 bolt, 3:42 posi; I'm just wrapping up the entire drivetrain swap this week. All new bushings, disc brake swap, RARE manifolds/ultimate X exhaust system, continental 10 inch converter, and several other things were just installed as well.

I have yet to reassemble the dash and wrap a few drivetrain items up; it will now sport an in dash tach and a rally gauge rebuilt by Peter Serio. It was also an AC car, which is no longer in use.

If I cannonball to get a few things done, I would consider bringing it, and all the factory literature for the car if anyone cares to see it. Camping one more time with the motorhome doesn't sound so bad either .

The website says the car must have a driveshaft loop if it runs over 13.99. I'd be surprised if this rule is strictly enforced. I don't think they would allow me to run for various reasons (partially listed above). What do you guys think? I'm still game to bring it anyway!

Attached is an old picture from the beginning of summer. It looks similar (as pictured) but the deep sump pan from the 455 is pretty evident now. The correct tips will hopefully be welded up by this weekend, too.

Colin W, If your GT-37 has a casting numbers correct 455 D-port motor in it with a relatively docile HFT cam (or the factory 067) in it with factory log exhaust manifolds, you would be good to race. You won't be legal to run with RARE Ram Air manifolds, unless yo have a 455 HO in there.

The TH400 with a 13" stock type convertor can be any year BOP short tail trans and the Olds rear is OK too. You will need to run 14" Rally II's since 15"ers were not available on GT cars. We give first year participants a little leniency with the driveshaft loop since we don't know how well it will run, but if you are running low 14's, we will look for it the following year if you attend. Track rules, not ours.

Hope you can come even just to spectate Colin.

Dennis

[Colin W]

Dennis,

Thanks for the clarification. The motor has 6x-8 heads and an xe-284h comp cam. It should run mid 12s. I recently purchased a set of five correct 14" KU rims for the car; however, they're not on at this time. I may go just for fun, and do one shake down run or two if possible. I'm definitely not trying to compete or win any awards.

[SD455DJ]

Colin, The only cars that get on the race track are the cars that pass tech and get assigned a number. So, you won't be able to make any passes during this event.

Sorry, Dennis

actually you have an additional week, get those items fixed and bring it. The Pure Stock Drags are Sept 16 and 17

[gloryrestoparts]

well, as some have seen in another thread, it doesn't look like my car will be there since it's currently getting repaired. However, I will be there, just not sure which vehicle. Or maybe I'm towing my buddy's car which we are working on at the moment.

Colin, Like Chris said, you have a whole week to work on the motor so youo can bring it out for the best fun on four wheels. You'll need a 7041268 Q-jet carb, p/n 481733 cast iron intake, #66 heads and the proper A/F body exhaust manifolds. What's nice is all these parts are cheap to buy and when rebuilt properly will reward you with high 12 second ET's at 105+ mph with your 3.42 gears and a good 2-1/2" mandrel bent "X" exhaust system (Pypes) with the Ultra-Flo mufflers. You can bump the compression legally to 9.5 to 1 and rum 93 unleaded.

[Colin W]

Dennis,

By no means would I ever consider pulling apart a freshly rebuilt 455 to run at a pure stock race. I appreciate your efforts; it's clear to me that your interests and motives are distinctly different from mine.

I will not be racing nor spectating.

[SmallHurst]

Come as a spectator. Once you do you will be hooked.

Everyone who has done this loves the event.

[unruhjonny]

I love the premis of the PSMCD;
I can't wait to attend one of these years

[SD455DJ]

Thanks Rusti and Jonathon! It is the most fun you can have on four wheels. I know Dan, Lyndon and I are so jealous of you guys racing and having fun while we work 6:00 am to 8:00 pm for three straight days, but we also appreciate all the thanks we get for putting on the event that makes it all worthwhile.

Colin, don't get me wrong, I really like your GT-37, however, this event is tailored specifically to pure stock factory muscle cars. We aren't naive enough to think that these cars are just as they left the factory and realize that many have lost their original drivetrains and were replaced with the same from donor cars, junk yard dogs, or pieced together over the years, but all striving for "numbers" correct originality. Many miraculously are still numbers matching. Many of the motors have been rebuilt more than a few times and have replacement components for pieces that are long gone (cams being the primary component). We developed the rules to keep the cars as close to factory as realistically as can be expected 40 to 60 years later. Some cars are completely original and unmolested while others are purpose-built race cars built to the maximums/minimums allowed within the rules. The thing they have in common is they both are correct in regards to casting numbers, part numbers, codes and equipment. And both are equally welcome to race. It's not about who's the fastest, but having fun and helping each other with tuning and driving techniques.

All cars that enter go through tech that check for all the correct casting numbers on the engine, proper transmissions and rear ends by marque experts we enlist for the event (see the website for all the rules). All new cars to the event that go quicker than mid-13's, we invite to the tech tent to check vacuum, compression and displacement, pull a valve cover and check rocker arm type (should be stock, no roller rockers), ratio and valve lift. Veteran cars that have marked improvement from the previous year are also invited to the tent.

As you can gather from all this it is about how fast you can make a stock muscle car go with correct factory drivetrains legally. This race attracts the guy that worked hard to build a gorgeous concours correct show car that has won enough trophies over the years and is tired of the static displays and is eager to feel and hear what the cars were meant to do in the first place.

Colin, please come and check out what we do in the middle of a corn field in mid-Michigan with a bunch of other like minded car nuts. I think you'll think differently.

I also have a 455 powered LeMans that isn't stock, but I love the car and it's power. I can't race it at our event, but I didn't build it for that anyway. I appreciate what you did to your car and you should drive it to Mid Michigan Motorplex and enjoy some amazing cars running incredible times. Yes, the only cars allowed to run down the track are the cars that pass the pure stock tech. There is no test and tune or bracket racing for any other cars this weekend. So, I meant nothing personally to you in my earlier post. I was just adding to the comment that Chris made about having a whole week to change your motor back to stock. I know that's crazy to do, but I also know some crazy people that are actually doing that right now, converting a FAST car back to pure stock trim for this race. Talk about dedication to a cause.

Please don't take offence to my comments and I apologize if I came off a bit abrupt. That wasn't my intent. I thought you might be serious about racing and I wanted you to know what we look for what you would need to do to be able to race.

Hey Dennis, Rex Carpenter here. I guess after reading your post my 73 GTO won't be able to run there either. This engine is a 413 (400 + .60) with round port E-heads a RA IV cam RA IV exhaust manifolds Performer RPM intake, & a Q-jet. $ spd. with a 3:73 to 1 rear end. LOL. But maybe my new engine next year a 455 + .60 over to, & most of the same pieces from the 413. I love my RA IV cams. 2 years ago with a 455 + .30 over it went 11:77 @ 122, I'm hoping for a bit quicker this next year with the new 469. With a trick intake system on it.

[SD455DJ]

Hi Rex, Ahhh....no, but you should build a pure stock motor for the car with all the factory pieces. That would be cool to see how quick we could get a big '73 GTO with a 400 motor and M-20 with your 3.73's go. A couple years ago we had a '73 Olds 442 Colanade coupe which surprised us with mid-13 runs. He was quickly invited to the tech tent and was completely legal. The owner rebuilt the drivetrain for the race and it really attracted a crowd in the pits. It was a really nice unrestored car and loaded too...burgundy with white top, stripes, and interior. It weighed about 4200 lbs, so not a light weight. It can be done.

Dennis

Dennis,

So you are telling me I have to take my twin turbo LS motor out for this race I guess I have some work to do but I will be there !
