Based of the mph on the dyno sheet, at 6000 rpm you have 14% slip. That's a lot.

Tin, it certainly feels like it wants to leap off the dyno. The converter was tightened up a bit from the 4000 stall that it was, but I think you bring up a good point, something for me to investigate. I will just leave it hooked up to the dyno till this weekend and try it again. How much slip is acceptable at top end?

x2 just was wondering why his chassis dyno #'s so low with his combo. I figureing he would be around 750 to 790 at the rear wheels.

The smart move would be to call Ceralli Comp. if you have questions about how to improve it.

Brian, I agree but my 455 went 465 rwhp and ran 10.90. I'm sure I will eventually get 560+ rwhp and at least be able to cover a 10.20 1/4 Mi. then drive it home listening to classic rock. As of right now I have +90 hp and + 50 lbs tq from the old combo. Will that get me to a 10.20? Time will tell for sure. The torque peak was 4950-5000 rpm and the HP peak was 6200 and very flat, which I think is good for overall averages. The split between the HP and TQ was about 1200 rpms. As I'm gathering all this data I'm trying to figure out if I could go up to a 1250 carb, as mentioned earlier, and /or is the intake doing its job based on cam dimensions, cubic inches, HP and TQ peaks. I feel i'm an adaquate tuner but I also know i'm amongst real pro's and will listen to sound advise.
