Hey Hopper, dilemmas!! I love those sort of problems. I would go sbc stroker. If you are at all concerned with fuel economy, remember, the bigger the cubes, the thirstier they get,... they just need more fuel.

It may be too late, but a 700R4 would have been nice, just because of the O.D. The lower the rpm while cruising, the better for fuel economy. Another added feature with this tranny is the wonderful low first gear, 3.06. The first/second gear ratios are a natural punch off to highway speeds, which is where most of our rodding is done anyways. Hey, have fun!
