Hank, I'm just using the larger powerglide valves - I don't have the tranny. Mine is an sm420 with a Gear Vendors O.D. The rear is a posi 3:90
I will still be using it as a truck so I'll stick with this. I guess what I'm going for is truck that will look original, still be used as a truck and flow with modern traffic. I'm pretty much there except the 235 doesn't like the hills. Especially if I have a load.
