106 lsa
106 lsa .239/.251 .570/.570 106lsa I was running this cam for a long time when I had my heads and headers before I blew the motor. It ran awsome. Now I have stock heads and exhuast manifolds. The car would barly run with that cam in it. I tried to tune it and had no luck, pulled it out and put stock cam back in. Has anyone else ran this kind of cam? What do yaw think about it?

never made it to the track or dyno but from racing on the street I was keeping up with guys running 402s with cam and heads. My motor was as listed in sig. It pulled really hard all the way till about 6600rpm
A cam with that much overlap demands an extremely good flowing exhaust. It will not tolerate back pressure and this would cause serious reversion into the intake manifold and kill power. Long tube headers with high velocity merge collectors, 18" open header entensions or a well designed header-back exhaust are needed to extract the most power from this cam.
