Mike,
I have found the LS heads make more power than the formulas for traditional heads. More like RR and spread port heads. I have a fudge factor when doing LS engine models. I believe his concerns with the T-Body air flow are justified, but not as important as with traditional heads. I've never done a carb or injected restricted LS engine. The closest I done to a restricted one is a 5.7 bracket deal with a good 750.
