71, TQ AND Intake design.......But thats only if everyting is truely stock. Toss on a stealthy 800 cfm AVS, port the intake, etc. and the 70 might come out on top, of course the TQ car could then up the ante with a bigger TQ and ported intake as well. BTW, if anyone thinks the pass side exhaust manifold difference would give an edge to the sexier 70 design, I've dyno tested both, 1-2 hp difference, so basically nothing.
