"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."

I wouldn't have guessed that. The outlet is like 2.5 vs 1 7/8 plus the pipe diameter has the be smaller as well.

OK so we think 71 is king, how much better do we think a TQ is over a AVS? Take my Duster that has run a best of 13.20 how much faster is it if I were to swap out the intake and carb? A tenth? Two? If it is 5 to 10 hp it won't even show up on the strip.
