Thanks everyone. My compression is about 10:1. My cam is a Comp Cams hydraulic roller 236/
[email protected] with a 108LSA on a 106 LC. I've just read an article that Hot Rod magazine did comparing a RPM Air Gap, Victor Jr., and Super Victor on a 410 sbc. They tested these as cast and ported. The Air Gap was better throughout the entire rpm range than the Victor Jr. when ported and not that far behind as cast. On their particular setup the Super Victor was the best. I know I've got pretty small displacement for my big heads but it loves the flow. I run a RPM Air Gap right now. I have a Victor Jr. to try but maybe I'll just port the RPM and sell the Victor Jr. Thanks again you guys are great.
