What was your total timing at? I am betting 28* or less. You can throw more at it and make over 400 I am betting. Seams like a conservative tune.

More timing doesnt always mean more power. I'd rather be safe than to squeeze out 1-2 more hp.

Just try it on the dyno and see. That cam will like a lot of timing. It is not like a small cams.

not knocking on it at all, but I would assume with full bolt ons and stock heads you would put down more then 391rwhp with a cam that big.

Did you shim the springs? Tuned? Almost 60hp increase. Not bad.

The T-ReX does seem to be a bit inconsistent. My full bolt-on (sans 90/90) has only managed 405 on three different dynos.

Perhaps it is the springs. I'm running unshimmed Patriot duals, but haven't seen any float.

I would be disapointed with those numbers out of a 242 248 cam.

springs DO make a difference, ive seen it tested with different spring setups and they carry out differently, my cam peaks at 6700 rpm and then flatlines for a few hundred and then drops off, yours is peakin well before that, im running 29* of timming, another guy was runing 30* of timming, i run 93 octane and i drive it in the heat with no trouble, also make sure that it was installed correctly, and lastly, get you a 90/90 fast setup, i had a bud portmatch it for me and i picked up 20 over the ls6 intake.

The Patriots have MUCH more seat pressure than the cranes. So I do not think power is low due to not shimming. Not with the Patriots. Most guys seem to shim the cranes .030. That is not going to bring those 112lb springs to Patriots 140lb. May want to be sure you lined it up dot to dot. Or if there is extra slack in the chain.

It's possible the cam is off a tooth. Looks to be advanced because of such an early peak.
