hey, seeing how this has become so popular recently, i figured id ask some of you guys in hopes for someone with hands on experience with an answer. how does the runner length in these manifolds stack up to the later version of manifold? im mainly trying to build power low in the rpm range. i want a car that is quick and responsive for every day driving and from what i understand, lengthier runners will speed up the air charge into the cylinders and help on the bottom end of the trq curve? ive read that people say this manifold swap is good for 4-5whp but where in the powerband? thanks in advance for your help.

the runner lenghts are the same. the big difference is the runners are larger in the early 2000 intake manifold. the current ones, the runners squeeze down to like 1/2" right before it enters the cylinder head.
