1957 chevy in stock

[Dave Noll]

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 ?

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.

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

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

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.

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.

A mid plate to use stock type frame mounts?
