Thank you, The cam profile with a carburettor setup has 468lbft @4000rpm, and 400lbft@5500 420hp495”/.502” Lift, 220°/224° Duration @ .050”, 112 LSA, a different option they tested is 450hp[/B]: .510”/.521” Lift, 231°/236° Duration @ .050”, 111 LSA with 488lbft @4000. So the first cam seems good. I don’t know if it’s worth looking for a different cam with flatter curve, if that’s even possible. The TPI will probably make it worse. I can use large runners, these will raise the torque by like 40lbft everywhere according to a test I’ve seen. Probably they won’t be able to produce as much power as the carburettor configuration which has a smoother flow. I’ve seen test with as much as 80lbft reduction when using 11 degrees of total advance but for that I plan to install and EGT. I already have 1 extra slot for AFR and 2 more at the front of the preconverters (these are 100CPSI metallic).
