Those are real good times considering you have issues in the upper RPM's. Are they fuel or mechanical related problems? My setup peaks at 63-6400 and only drops about 15hp at 7100 rpm so I kept upping my shift point and found 7000 seems to run good. I would highly suggest getting a shift light, I have the Raptor from WS6store.com and it't under $150 and can program and install easily. You can probably knock some ET off just from not having to watch the tach and concentrate on driving and also much more accurate than the tach on the dash. I will post results from the gear swap, I really don't see how it can do anything but improve performance as it should help my 60ft (as long as I keep traction) and will put the engine in peak power across the finish line instead of 500 rpm below peak. I'm also considering a set of front skinnies to reduce some weight and hope to hit my goal of 7.2/7.10's from the car.

I believe a little of both, I am taking the engine out right now actually to freshen it up. While its out I'm also swapping to le3 heads. I did find out what pistons are actually in it, they are -22cc forged. So I am pretty happy with what it done for the first time on slicks.
