So best case - worst case, how much HP or ET would a full port job of that SV intake be on an engine that could utilize the flow? Say a good 408 with heads that flow 275ish.
A Victor340 would be a perfect intake for that flow with a gasket match and plenum blending. Super Victor would too with more work. Both are very capable of running 9’s@3000 pounds on a 408 with the right combo and a few more head cfm.
