Camshaft And Valve Timing Event Articles

It’s obvious there are many theories. I first contacted Jones with the specs shown in the other thread. He recommended a 316 adv, [email protected]” .378” lobe (.604” before lash) on a 110lsa with max power at 6700-6800? I got to thinking, asking here, thought it was too big, decided to lower my max power rpm a little, 6500. Got a revised recommendation from Jones. A 304 adv, [email protected]” .364” (.582” before lash) on a 110lsa with max power at 6300rpm. Both single pattern using .875” lobes. Ok, let’s try another source with same build etc. Howards came back with a 274 adv, [email protected]” .384” (.614” before lash) on a 108lsa, single pattern .904” lobe. The first one with 875 lobes with big seat duration, good lift, second one still big seat duration, with what I’d consider very mild lift 875 lobes. And then the last one with very aggressive 904 lobes but less advertised, @.050 and on a 108lsa and 58 degrees overlap. The first cam is an outlier, the second Jones and Howard’s are very different but of the two I’d pick the Howards for the area. But timing events I’m not sure on. And I’m not going with max aggressive lobes. Now eyeballing Bullet, and liking some of the older Ultradyne lobes. Still waiting on reply’s though.
