looking to upgrade the 3 speed auto trany on my 70 chevelle ss 396 to a 4 speed over drive auto trany any suggestions ??

I like the 200R4, if it had a turbo 350 there is no driveshaft mods needed, just the crossmember moved back.

My little brother just installed a 700R4 in his 73 RS Camaro that was built to hold up easily to near 700hp. He`s running a mild 383 stroker but wanted the assurance that the trans would hold. The company he got it from was called ProBuilt out of California. The people there put a healthy warranty on the unit and told him if he broke it, they would fix it!! I think you can buy them in different stages as to suite your needs. Heres the link to their webpage; http://www.700r4l60e.com/
Might want to give them a shout.
