Let me start of whit that im no expert !
I tested a 1970 Challenger 440 5 speed trans 4.10 and that car had a Comp Cams 23-711-9 roller cam that ran realy strong.

My car have a 505 stroker roller hyd cam that i rev on the street to 5500 rpm whit a 4 speed trans and that works fine on Hughes Engine parts but i do have some noise that come and go at sertain rpm´s and that has been that way since i started that engine up the first time and i gues that if a cam lifts around 0,600 on rockers some noise sould be expected even how tight everything is !?
