I have a 1984 Camaro that had a 305 and auto trans. I didn't get either when I bought the car. I'm swapping a built 4.3 out of a 1999 GMC Sonoma in it with an edelbrock intake, 500cfm performer carb, headers, dual exhaust, 3.08 gears, and a 270hr comp cams camshaft (.500 lift and 215 duration on exhaust and intake). Im hoping for 300hp at the crank but iI think I'll fall a little short. I want to know if an nv3500 would be a good choice for this. There's one for $500 low miles on Craigslist that I'm thinking of buying. It's either the nv3500 or a t56 and I'm having trouble finding a reasonable t56. Im also concerned with the shifter lining up with where it needs to be on the center console.
