I understand it is not your original question, my thought, sure would make a good GT or Crate Motor project.

To answer your original question, to my knowledge a 57 is acceptable in stock with any of the original factory engine combinations. [as posted above]

Also, how cool with it be to run the 283 with 2 carbs. [a 283 - 283 horse was available in 57 with four speed. it used a low profile 2 x 4 intake]

[ss wannabee]

Larry...the 283/283hp engine was with Rochester Fuel Injection and Duntov 097 cam....

There were 2-2x4 carb combos...270hp with the above mentioned 097 cam...and
245hp with a regular hydraulic cam...Cylinder heads and cc's may differ as well so
one should check the latest NHRA engine specs to see what's permitted....

Was the 250hp FI engine (with regular hyd cam) available in '57 or did it come later?

[Dragsinger]

yep, my "old timers" is showing

also, the correct carbs and manifold while could be found, whew, talk about expensive.

The 283 4bbl can use the 459 327/250 intake now, plus a 3 speed trans..Not a bad P/SA
car.
The 283 / 245 2x4 deal would be more expensive to build. It would probably be somewhat faster , but I doubt it would cover the half second index loss.

I didn't think the 4 speed was available in anything but the Corvette in 1957?

That is correct and all the cars that had 4 speeds and hydros had to switch to 3 speeds or powerglides back when the rules were changed.

4 speeds were only allowed in Corvettes and 4 speed automatics or hydros as we called them were out...

Powerglides were not very competitive until Marv Ripes developed his small converters for them...His car that was driven by John Barkley was the only fast p/g car during the era of the hydro equipped sedan deliveries...He must have used that car to develop the converters for p/g's...

This change was back around 1968 or 1969. To many bogus combinations that were never really assembly line production cars.

Some racers tried 3 speeds but they were tough to work with and were mostly used in 55 and 56 cars with 265's....that always had them...

Now the modern rules allow 3 speed automatics in cars that only had 2speeds....so that sounds like a '57 could get a metric 3 speed........I don't know about the 4 speed vs 3 speed manual trans issue...

Mark, nhra has allowed the 459 intake on the 220/283 for over 20 yrs.
i set the t/auto record with it in 94 or 95 at e town. I remember all the stockers
/ super stockers you had at CT. dragway / CT intl. back when i used to go
with my old man. Isn't someone running a 55 chevy nhra legal stocker out
of the south Jersey area? Al jr.

I don't think we are going to see very many Tri-Five Chevys out there in NHRA Stock.
Too expensive, and the cars won't run very far under, even with the 459 manifold.
