Stroker small blocks - what intake?

In the range you specified, the victor may make more power. That 4" arm does some cool things, one of which is make the larger port/plenum work like a smaller one would. Same with carbs. The piston speed they generate really moves some air at lower engine speeds, so a large port helps, as opposed to hinders at slower engine speeds. As long as your heads can move the air (and they can), the intake can be a large port, and not lose much on the bottom. I think the carb and intake right now are the choke. The Victor may not clear a hood tho...
