Since I don't have the original engine anyway, I figured that I'd pick up a 350 to get a few more cubic inches. I have considered rebuilding the 283 that I have, just not sure yet.

I assume that the 283 will work OK with a 200R or 700R4? It currently has a powerglide, and I tend to get my trucks out and go, so it would be nice to have OD.
Yes it will work with either. Are you opposed to a manual transmission? A 5 speed OD transmission is a great combination with the 283. A T5 makes a good swap, or if you have the bucks for it a new Tremec TKX would be nice.
