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?

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.
