Default Any word on the #50 replica

Hello all I was wondering if any progress was made on the Paul Goldsmith super duty tribute car? I haven’t seen any thing and the car in a few. I remember it was coming along really nice. I always wanted a road racing 1963. Probably never happen at my age...if so maybe pictures? Tom’s SD intake would look incredible on it.

According to the Hot Rod article the car used the factory transaxle. Any info on what they did to make it last racing 250 miles behind a 421 SD ? Are there any technical articles or details available on the design and construction of these SD transaxles ? Photo's, Engineering Drawings, Specifications, etc ?

Tom, you said you "gave the drawings to Ken". Were those PMD drawings of the units or something else ?

I just find the engineering aspect of these units fascinating especially since they made so few. Did you ever have yours apart ? Where did they differ from the regular transaxle and what parts were the same. Do any engineering records or drawings still exist ? Why did they choose to retain the transaxle for the super duty's instead of using the big car rear axle like the racers eventually did ? Did their testing not reveal the inherent weakness of the Corvair style differential ?I'm assuming since you said you "owned one" (past tense) you no longer have it ?

This was the car and the engine it would have been behind.The engine is a FACTORY all Alu engine that I found at M/Ts back in 1964 and finally got my hands on it a built it.Tom

Yes agree %100. Way up here on the cold side of our country we have a road course racing series at lime rock park in Connecticut (on hold last year). it’s got some really cool nostalgic replica race cars. They aren’t the original high dollar collectible museum cars guys will try to get as close as possible mostly the paint jobs , car numbers on the doors, sponsor decals side pipes exc. and maybe some of the engine configurations. These guys are definitely not able to completely replicate exact factory race cars. Mostly from the Trans Am series races. Some are early nascar repos too. I thought it would be definitely a showstopper to see a 63 even with A conventional driveline show up for the events. Thinking of selling my 62 drag car to build a 63 road car.

I actually bought it with intentions to use it.Found out after that they dont have a differential.The axles are way bigger,the stub shafts going into the rear end are opposite of a regular 63 V8 car.The inside has a spline shaft that goes straight thru the assm and the stub shaft (female) goes over the steel shaft(making it a spool)The unit consisted of a basic 63 Tempest TQ 2 speed auto.Engineering made a 2 speed planetary system to attach to it to make it a 4 speed manual automatic.What ever gear it was indexed is the gear it stayed in until you moved it up or down.They used a hyd bearing mounted to the rear for the clutch and flywheel.I sold it when I fond it was not going to driveable on the street to Ken Freeman in OK for his real 63 SD tempest. I will post some pics of the assm ASAP.
Until then I will post a link of the genius I bought it from and you can read what he was able to build with one.Enjoy.Tom

Default Ahh thank you 406

I’m very interested I the road racing #50 car. Wish it lived to change that famous cobra/Ferrari battle. Sure Looked promising because of its 50/50 weight distribution. Of course recent super car technology is 50/50. I am aware of the low stress of road racing compared to drag cars. Really want to see how the replica was coming along.. I’m sure it can’t be exact replica of the one off goldsmith car but still way cool to see somebody getting as close as possible to the lost car. Thank you guys for the information on the incredible work that the factory has done. Looks like I’ll need face book. Aaarrrr I hate FB.

Thanks Tom...that's a lot to digest. Sounds like you could be a great source for several articles in "Smoke Signals" like the recent Dimitri Toth series. It seems the more information you post here...the more questions I can think of.
Just that all aluminum engine from M/T's shop sounds like a story I'd love to hear more about.

So the stub shafts and axles were fabricated by engineering, but the two-speed
planetary case looks like a commercial unit unless they cast up a special case.
What about the ring and pinion ? Was that custom ? You'd think if they went and beefed up the axles and stubs they would have done something similar with the R&P unless there were space constraints within the differential case. Was a stock differential case used or is that a "one of" too ? Was the torque tube and shaft modified in any way ? Did it connect directly to the crankshaft or did they use a clutch assembly up front too ? Sorry if this is too many questions...like I said, it's just a fascinating piece of engineering

Look at Roger Rosebush's facebook. It is nearing completion. My buddy has been working on it. I was helping. He is going to be at Norwalk.

Thumbs up From AMES Pontiac Tri-Power Nationals Page;

TempestGuys.com takes great pleasure in debuting their recreation of the 1963 #50 Pontiac Le Mans. The car is the result of seven years of effort and great expense to recreate one of the most famous, and mysterious, cars in Pontiac’s long racing history. It raced one weekend, victoriously, 58 years ago, and then disappeared forever. Now, it has been recreated and is making its world debut at the 2021 Ames Performance Pontiac Nationals.

Cant wait to see the car. I can only imagine the engineering behind the original.

The problem was the deal still used the 7.5 R&P.On the drag cars with slicks they lasted 10-12 passes.The other deal was 3.90 was the lowest avail.I gave the drawings to Ken when I sold him the SD transaxle and Engineering tooled up for what im told was a Xtra for each of the 12 factory cars,not including the 2 mule cars.Tom
