In an all out stock appearing build what would be the power difference between a solid flat tappet cam and a roller. 499/400 iron intake and exhaust manifolds.
Comp cams probably offers 30 SFT lobes and probably a 100 solid roller designs. Maybe share what you have now? Maybe ask opinions on a certain SFT lobe verses a certain solid roller lobe. The head flow info through 0.700" might be helpful too.
If you're using MM lobes with a 1.7 rocker ratio and comparing it to a High Energy roller w/ 1.5s with similar seat timing, probably no gain, maybe a loss. If you are comparing an High Energy SFT on a 1.5 verses a TK lobe with a 1.7 probably 70 hp.
