Good morning all,

I’m eye balling clearances before I drop the this combination back in to my 57 it looks like the driver side transmission mount is going to come very close to the idler lever support assy. I have removed the clutch shaft bracket but wonder if I’ll have a problem with the other assembly, or, if it’s just going to be really close.
Thanks for your help.
MikeH

Are you talking about the factory bell housing mounts? When I converted my 57 to a modern driveline, I took those off the frame and used side mounts on the front and a transmission crossmember in the rear.

I have after market bell housing mounts and factory front mounts. Will add rear tail support before I finish up. Will try to post pictures tomorrow.

I have heard that putting a rear trans. mount while still keeping the bell housing mounts will lead to cracking the trans. case.

Interesting. I had to slightly modify the bell housing mounts to sit flush to the housing but could see if they were not flush to the bell housing, it might crack with a little engine torque, if not during the mounting process. I’m not an expert by a long shot but cannot for the life of me see another mounting alternative to one I plan to use.
I could not post pictures of the fitment concerns in my earlier post but I am not in a rush.

Thanks Larry, I’ll look at this. It would eliminate the clearance issue concern with the stock mount brackets.

Chevrolet went to the side mounts/rear crossmember in 1958 and is still using that concept today. I recommend against using the stock front mounts and a rear crossmember.

That's interesting. I was told on different forum by 1/2 dozen others, if your doing the front motor mounts and keeping bell housing mounts to also do rear transmission mount or you will run the chance of cracking the 350 transmission case. Being the power glide was cast and the 350 is aluminum.

The 350 case is cast aluminum. The Powerglide is cast iron or cast aluminum. Either way cast cracks easily, whether it’s aluminum or iron.

1957 was the first year for the optional Turboglide transmission, a cast aluminum case transmission. Still used the front engine mounts, and the bell-housing mounts/transmission mounts. I've know guys who used front engine mounts with a rear cross-member/transmission mount, and never had a problem; other guys had aluminum cases that cracked. My first Bracket car was a 56 Utility Sedan with a BBC, and an aluminum Powerglide; the front had a Hurst saddle mount, with a lot wider "stance" than the stock front engine mounts, and a rear cross-member/transmission mount; never a problem. Ideally, use a kit to side mount the engine and a rear cross-member/transmission mount. If you really want to keep the front mounts, then use a bell-housing mount conversion kit, AND, a rear cross-member/transmission mount. I have a TH-400 transmission; it's actually a Switch-Pitch TH-400 that had the bell-housing cut off, and an aftermarket bell-housing, WITH TRI-FIVE MOUNTS CASTED INTO IT'S CONSTRUCTION. First one of those I've seen, and mostly why I bought the transmission. If I ever use it, I'll add a rear cross-member/transmission mount to it just to be safe. Cast iron is a LOT stronger than aluminum. I am Butch/56sedandelivery.

That's what I did after advise from others. I have stock front motor mounts with 327, so I installed 350 with Danchuk conversion bell housing mounts and rear transmission cross member mount.

Exactly that's why rear tranny support is recommended with aluminum transmissions
