FWIW: I happen to know that the mod list in that video you posted was incorrect. Thacker didn't have aftermarket or ported heads on that car.. it was SOME bolt-ons (headers, crappily done ported t.b., and a mail order tune) and a cam.. I sit and watched the mods go on. Not trying to butt in, because it looked like you won a few of the races, but just noticed the mod list was incorrect.
