Cam Experts: Lobe Separation Angle?

That depends on who you ask. I also don’t get excited about cranking compression either except in the fact that as cranking compression goes up, the tuning window gets smaller.

If someone isn’t into tuning and keeping a close eye on stuff then a lower cranking compression is a good idea.

What I’ve never seen is a correlation between cranking compression and detonation.

I’ve had over 200 psi not rattle (but you had to make sure the tune up was pretty close or it would rattle) and I’ve had 160 psi rattle like crazy.

That was GM garbage though. You have to work pretty hard to get even a decent small block Chrysler to rattle.
Yeah, I had a 360 in a 65 Valiant years ago that had 210 PSI and it never once rattled on pump premium once I got everything tuned. It did, however RUN better on 112 leaded Cam 2.
