Check out my post (#18).
Anyone know why we consistently see the dips in the hp/tq curves around 4,000~4,800 rpms with aftermarket cams? I'm leaning towards timing as the culprit, but have no solid answer/proof...

intake Runner & cam timing dynamics.Tight LSA cams exhibit this behavoir more then the wide LSA cams at least from what i have seen but that overlap quantity is dependent on total lob timming.

Hey Sean...thanks for the input. Hopefully, we can chat more about this when I have you put my LS7 clutch in for me next year. That is, if 'Santa' is still bringing his 1/2.
It'd be nice to get rid of that dip in my tq curve though. I could've swore it was timing related because the guy from PA who put the car together only had ~25* of timing there. I didn't try upping it to 27* while I was on the dyno (rushed for time)...
