Hmmm, let all Motion cars in.....wonder what class those 454 Vegas would fit; of course good luck any rust free bodies up this way lol.

That was the thing about most them, they were just about all available with only 4 speeds. That takes many out of the equation, since many people won't race a stick shift, kind of like it is self policing.
But back "then" GM was offically out of the factory thing to make race cars legal. There were no Chevelles to run at Daytona like there Ford Talledgas or Plymoth Super Birds. No LS7s like there were Boss 429s or race HEMIs. Yet we all scrutinize GM cars to the same standards as the factories that really were involved in racing.

COPO 9010 LT-1 Nova was available with auto trans. TH400

Same as LT-1 Z 28.
Seen several Yenko Dueces with auto back in the old days. Hurst auto stick shifter if I recall.

Silver Copo 9010 Nova from Canada has auto. It has been in several muscle car magazines over the years.

Jerry,

I talked to some people in the Motorsport group at GM a couple of years ago for someone that was interested in build this combination. At the time they told me that they were getting a lot of flcak from NHRA about paper cars. I, like many people realize that these cars were real but they have become an obscure forgot entity. You might be able to make another run at this again. I can get you a contact if you really want to try again.

Funny it may be, but that was the story that I got.

If GM served NHRA the same or similar dinner and dessert that Shelby Served NHRA, we might get to see some of our greatest and rarest classic muscle back in the stock eliminator.

olds 442, I beleive that the edelbrock olds heads use stock style(small block chevy) rocker arm set ups, not the trunions. If I am wrong I apoligize. I sure would like to see it happen tho. GM's rule!

Bruce, I don't doubt that one bit, not at all. It does not even come close to surprising me, either.

The Edelbrock Olds head uses regular studs and guide plates. However, it would not be a problem at all for Edelbrock to make a run with 5/16-18 threaded rocker bosses to accept factory valvetrain. They did not alter the valve location or angle on the Edelbrock head.

You do not need to run the factory rocker bosses anymore, the rules are already changed to allow guide plates and studs.

Refer to:

Stock Cars

Camshaft/Lifters: Delete last sentences of paragraph and replace with "Larger diameter pushrods permitted. Pushrod guide plates permitted. Cylinder head may be clearenced for larger diameter pushrods."
