Need cam advice from you experts :-)

What rpm did you shift at when you ran it at the track? The reason I ask is that if it was my car I'd shift that thing at no less than 6000rpms, but you mentioned you have the limiter at 6000. I think you might have more there now as it sits if you rev'd it a little more. You have heads and an intake that should make power well into the 6000rpm range, so cam it accordingly.

Thanks KillerCanary.

I was just searching the forums and found this older thread I started. I obviously missed your post somehow.
I generally shift at 5500 rpm but I'm a newbie to the track. I've been 4 times and have about 20 passes under my belt. My best ET is 13.66 @ 103.20 but my highest mph trap is 104.6 with a 13.69 ET (all season street tires ). I guess Ishould add that my car is full weight (no weight loss reductions) and I have 3.55's. I'm reving at around 4800 across the trap...that's not good.
I found my up to date dyno graph and it indicates 280 rwhp bang on and 311 torque. Again this is prior to pullies, and I've also since added a shifter. It appears to be a tad rich at 2500. I know it's lean the rest of the way though. My plugs are white. Tomorrow I'm going to dyno tune in an AFPR. Yes I'm using a stock FPR as well.

Thanks folks on the cam info.
Killercanary, thanks for the tips and I'm taking the car in for dyno'ing this morning. I know my tach is accurate because I've compared it to the dyno tach and rev limiter. I'll try shifting higher next time. I'm probably losing out on some MPH with the 3.55"s? Peak rpm across the trap is about 4800.
I'm also going to try locking in my timing with spout removed next time I go to the track. That may give me a couple of mph as well. It did for a friend of mine. He locked his timing at 36 degrees spout removed and instantly picked up his ET's and mph.
