Well, I'm going to contour it close in config to the non-W2 Holley Strip Dominator...but that's about where the comparisons end because I would expect the runners, the diveders, etc. to be all different. In fact, the W2 intake has runners which are nearly 0.5" taller...as far as to what actual runner volume that translates to, I have no idea. It certainly is a bigger intake.
