cam duration

I am (almost)...Hughes HE3844AL hudraulic flat tappet...238/244 @ 0.050"....verified 9.7:1 static CR...fast ignition curve (21 initial, 38 total)...no detonation on 94 octane, dynamic compression is 165-170 psi.

In fact, I just picked up my heads from the machine shop as I'm going to a 10.5:1 static CR...gimme a week or two and I'll report back....it'll be a bit hairy I suspect....

My cam is much bigger then what you are looking for though...so this is not a recommendation regarding cam size but rather a point of reference for what is working for me.

This is no help at all. Your cam, when installed at 104 will have an ICA of 67 Degrees.Your Scr is stated as 9.7. Comparatively speaking,these are not even on the same planet.
