There is a point where high velocity meets restriction. Just because the runners may be small does not mean the velocity is always going to be high either. And just because the air is screaming down the runner does not mean enough is moving to fill the cylinders. It takes a lot more than just guessing to build a good combination. But the number do show that a 3400 will beat a 3.1L on every aspect of performance.

granted, i just didn't think i needed to go that far into detail. as far as the 3.1/3400 comparison, well, it was more of my Z24 vs. my GA is all. not to mention the 3400 is more efficient as well.

Go to the WOT-Tech Store and look at 3x00 roller cams... there are tons and the price is 330 IIRC and then add in custom pushrods. All and all I think the cam, pushrods and a set of the comp springs (not always needed) will be around $600-700, I think I paid 650 for my whole setup.
