700R4 would be a good one. I changed my 350 automatic out to a 700R4 and I love the R4. I can't help you with bolting it up as I am running a 350 engine. But I do love the R4.

On the rear end change out..... I did this on my 52 panel. Dumped the torque tube and installed a 55/56 pumpkin. Later I found out that SOME of the later model trucks, say maybe 60-62 I think it is, had a higher gear ratio. Now I wish I had kept looking for a higher gear as I am running a V8 in my panel. All things considered the 3.90 may be the right thing for your 235 engine especially if you can figure out hooking a tranny with OD to it.
Keep us posted. I'm interested just so I'll know for the future.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
