had a 420 behind a 350hp 327 in my '63 1/2 ton with 3.73 rear. It was pretty sweet setup. 1st was no longer granny, but still didnt use much. No overdrive, but neither di the old camaros, chargers and mustangs. Upper three gears were all synchro. I'm with Ed. the T5 out of s10 is lighter duty but there are other t5 options.
Hey Larry,
I'm hearing that the 420 is a pretty bulletproof trans. Unfortunately mine isn't going into reverse. I'm thinking something isn't meshing in there so I'll be taking the top off this weekend and having a look. I'm not too concerned about an O/D gear since I don't plan on doing any freeway driving with it, just back and forth to Home Depot and a car show or 2.
