Has anyone done a T-56 Install in a Chevelle or EL Camino w/ a big block? What problems are involved? Who makes an adapter or will a small block bell housing work? I'm aware of need for black box to connect speedometer, but are there any other problems.

i haven't done it but i know a fella that did. he said he'd never do it again, had to fabricate EVERYTHING almost, and it was hell. he finally got it going after a lot of trouble, i'd love to have one but will wait for a direct bolt replacement to replace my munci. or a kit that makes it ez.

I've dreamt about putting one in, that's about as far as i got after i saw the price tag. I think i'm with chev-hell on the waiting for a bolt in. Let me know if you do make the swap.

You can buy a retrofit T-56 box from several GM dealers. This T-565 trans is made to retrofit the T-5 used in 83 to 92 Camaros/ Firebirds. it comes with an adapter plate to bolt it to a standard bellhousing and has a longer input shaft for use with a standard flywheel and clutch assembly with 26 splines. It costs $2200 + shipping from Jim Pace Parts.

The Takout from a late model camaro/ firebird is a lot of work, and you need to use and adapt the late model hydraulic actuated - pull style clutch assembly and need a special flywheel and clutch, which are very costly.

I put one my '70 SS (the car is featured in Super Chevy Feb 2000) and it's the best thing I've ever done. Using a OEM Camaro box is by no means a bolt in, but worth the effort. There have been several articles on this. If it's going to see some abuse, make sure you get the one w/ the 2.66 first and .50 sixth gears. These are strong transmissions.(conservative 450 #-ft). I run a 4.56 gear now and can cruise 80mph all day.Wonderful!

Do you have any good links for a install? I picked up a t-56 out of an LT-1 car that I am planning to bolt to a 502. Any and all help would be great.

Take a look farther down the main forum page and do a search in the transmission forum. Plenty of reading to get you started. This thread you replied to is 7 YEARS OLD!

Ya, I noticed that after I replyed.

Well, I guess using the serach function when asking questions is good, even if it really digs into the past....

In any case, take a look at thirdgen.org in the drivetrain forum. The swap is discussed in a level of detail that should answer any question you have. About the only possible difference between a 502 and anything else, is the part # of the flywheel you might have to use; everything else is the same.

Also try protouring.com and do a search.there is alot of info on there also. i searched it a little bit and you can just get an LS1 t56 by the adapter that summit sells and you have to use a extended pilot bearing and it will bolt to the regular scatter shield.

Check out this site. These guys really know what they are doing and have the proper kit for your application.Good luck!
