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]

Re: 1957 chevy in stock
 

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?

Re: 1957 chevy in stock
 

yep, my "old timers" is showing :)

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

Re: 1957 chevy in stock
 

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.

Re: 1957 chevy in stock
 

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

Re: 1957 chevy in stock
 

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...

Re: 1957 chevy in stock
 

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.

Re: 1957 chevy in stock
 

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.

Re: 1957 chevy in stock
 

Hi Alan...I should have said the 57 283 /220, (now 215) can now run the 459 intake also, thanks to Captain Jack and his diligence. (see recently updated specs)
Say hello to to The Old Man !

Carl Libucha of Easthampton MA is running a 55 Chevy in P/SA. He went to round 5 in stock at Epping last month.

Re: 1957 chevy in stock
 

There's another '55 Chev NHRA Stocker run by that girl in Maryland.....

Re: 1957 chevy in stock
 

That is Shelby Hurley our own watermelon queen! Her dad, Steve has one in s/s she has drove hers in stock but also s/s. from what I understand they just got another one, but that's a story for them to tell

Re: 1957 chevy in stock
 

Well, I've got a nice 2 dr hard top sitting in my shop that never gets driven. It's a bell air with an inline 6, 3 on the tree over drive & 4.10 gears.
I love the car, but never get a chance to use it.
thought I'd make it into a stocker??
That way I WILL do something with it!
Thanks for all the info!!
I need to see what the powers at be have to say....

Glen,

Tried to send you a PM but your mailbox if full.

Re: 1957 chevy in stock
 

I learn so much from youse guys. This post was interesting as I have thought seriously about a lower class Stock class car for awhile. I wasn't aware that the 55-57s could still be run. I have a 57 more-door belaire setting in the garage. 283 -power pack ,powerglide. If in fact the car could run with a metric trans,would the four door allow me some advantage -jumping class ,ect?
Can someone tell me what the car would have to run for the NHRA index?
Did i mention ,I really like this car ,but i seem to ignore it way too much.
Thanks

Re: 1957 chevy in stock
 

Looks like not much weight difference with a 4dr.

Look it up here:

Re: 1957 chevy in stock
 

OK I'm just a Ford guy asking this. A 57 has the motor mounts @ the very front of the block and, if I remember right, a mount on each side of the bell housing. Then the trans just hung from there. @ least this is how a 57 Pontiac is, (I had 1). My question is this; how, under Stock rules are you going to put a Metric trans in that ? :confused:

I've blown up a lot of pics on this site but I have NEVER seen one that deserved it more than this one !!!!!

Re: 1957 chevy in stock
 

So I assume I would not be allowed to install a crossmember, but would need to fabricate a side mount setup.?

Re: 1957 chevy in stock
 

David, The aluminum PG has been a super-ceded replacement for the cast iron one for a long time. Of course, it has a rear mount, same as a T200. So yes , you can use a rear cross member to hold it up.
The front mounts are far enough apart to hold it in place. Not exactly the same as the early Corvette, but similar.
You could add a torque strap , and I believe it would be fine.
The early Pontiac was a bit different. It was a horseshoe deal with a center pad.
That wouldn't work without bell housing or side mounts.

Re: 1957 chevy in stock
 

I think the question kind of boils down to: Can you legally install side motor mounts on a Tri-Five Chevy for stock eliminator?

Re: 1957 chevy in stock
 

Jimmy, You and I wouldn't get away with it..Maybe someone else would.

Re: 1957 chevy in stock
 

Thank You, Mark. I don't think I would be comfortable with that long distance between mounts on the Chevy, but somebody must be running it that way. Yes the Pontiac had one mount @ the front & it was bolted to an iron timing chain cover.

Re: 1957 chevy in stock
 

I ran SS back in the 70's with my old 57 wagon, (Still got it, turned it into a street car). I used the old '57 265 block, so it didn't have the side mounts on the block, and I had an aluminum Powerglide transmission. I made a rear crossmember, and fabricated a drivers side torque arm that bolted to the bellhousing and had a mount on the frame with a rubber cushion between them. Worked fine with a small engine/low hp.

Re: 1957 chevy in stock
 

A mid plate to use stock type frame mounts?

Re: 1957 chevy in stock
 

Not necessarily the best, but the idea may work in low hp setup.
