1963 CHEVROLET 427 Mark II “Mystery Motor” Engine
An official American Manufacturers Association (AMA) ban on all factory sponsored racing activities was brought on by negative public reaction to performance cars being driven irresponsibly on the street. Despite the ban, Chevrolet engineers continued to supply independent race teams with the equipment needed to win races and keep their cars in the public eye. In 1962, General Motors engineer Dick Keinath designed an all-new engine that generated over 500 horsepower. Because it was delivered secretly to a few race teams, it became known as the “mystery motor.” Junior Johnson and Mickey Thompson were among the select few given these motors. After a race at Daytona in 1963, General Motors recalled these engines in order to demonstrate their sincerity about complying with the racing ban. But not all the engines were returned to the factory and a small number remained in private hands. It was not until 1966 that a 427 V-8 was not available to the public in a production Chevrolet.

Nice to see the photo DOG. Actually, Red Fox received most of the equipment, complete engines and parts. It's a shame that written history doesn't credit him more with being such a key player with Mr. Keinath's engine.

PS: notice the FORD cast iron T-10 transmission behind it! Care to venture how that happened??

Dog,
The Ford transmissions were more popular back then because of their higher strength (high nickel gears, etc.) The Pontiacs even ran Ford Transmissions. Nascar's only rule was that it had to be a standard trans.
I don't know who owns that engine assembly that is in the Petersen Museum but my guess is that is came from one of Smokey's auctions along with the trans. The front case is probably a GM case so it will bolt up to the Chevy bell. (or they may have just modified the Chevy bell, but I doubt it).
I don't know who put that assembly together for display. It could even be a 3-spd. After all, they weren't drag racing... 3-spds were used a lot in those big cars.

That is VERY cool.........

Now I have to ask you, just how did you happen to come by that? Did you or someone you know order parts from him? You don't have to answer if you'd rather not. I'm just curious.

I am not sure, but I would imagine I got it when I went to Louis & Rex's garage (see 1st post)
