Hey guys had a question

Thinking about picking up a 72 Chevelle Malibu. Has a 383 stroker, Turbo 350 non overdrive transmission, with 4.11 gears. Cruise RPM is crazy high.

If I purchased a 200R or 700R4 (both with overdrive) to drop the cruise RPMs would it be just a simple swap or would any modifications have to be down?

Thanks

The 200 is pretty much a "drop in" since it is the same size but the 700 requires shortening the drive shaft 3" and moving the cross member back which changes the length of the park brake cable.

A well built TH2004R is the trany that I am looking at for my car !

And like Dean says it is the easiest way to go !

Is the "typical" 200-4R strong enough to be behind a mild big block, or healthy small block?

I know the Grand National transmissions were able to handle them, but I'd imagine they have some different internals, and aren't like what you'd find in a cookie cutter 6 cylinder Cutlass or similar.

There's a local guy to me that has a rebuilt one for what seems an OK price. I have a T-400 so I know the front yoke is different, but hate to take the leap of faith and break it with a little sissy 396/402 engine.
