Came across this article on a 408w build in poppular hot rodding magazine they built there 408w with very simular specs to what im building , same size carb , same intake (rpm air gap) same heads , the cam they used was a hydraulic roller 230/236@50 513-529 lift mine is a solid roller 242/248@50 608/614 lift so mines  a little bigger , they don't mention comp but im going 11.2.1 i don't think they would go more as there fuel isn't as high in octane as ours click on link below and see results , all i know is i better start an account at my mates at tempe tyres ;x go the hooligan!
