Are you talking a 10:1 408-416 street motor, 3000 stall and 3.91 gears? The airwolfs (airwolves?) would still work well but probably not as well as SDSS2's for that combo....remember the shadybrocks (can I coin that? ) are extremely fine heads, but on a 10.1 motor they are more a 2200-6200 powerband, where as the AW220's are more a 3000-6800 head. Ex: The best overall intake for the 3400 pound 10:1 combo Imentioned would be an AG RPM, but that intake won't flow to the potential of the AWs. The AW's (as well as the IMM max port eddies) can fill a niche between standard ported eddies and the W5 Indybrocks where that extra 500 RPM above 6000 can be put to use on the right 408-416 combo.

These could also work on a high strung low geared 340 but were talking 4200 stall or a stick and 4.30-4.57 gears in a Light car with a very carefully selected cam if it's going to see any street time. I LOVE those kinds of combos, but they're not for everybody.

A lot of people still make the More is better mistake, that's all I was saying. For the combo you describe (assuming the same Cr/stall/gears/wt) the 4.125 crank and 430 cubes would probably work great with the AW's and the right cam.
