>>>>I run BFG Drag T/As on the street, and a 12 inch Mickey Thompson slick at the track. Have yet to have traction problems at the track or the street- suspensions pretty tricked out. I have smeared 4WD Syclones on the street- their traction didn't get 'em too far ahead of me. :-)

>>> Ah...a nice soft compound tire (the Mickey's). The problem with the Syclones is that they're automatics. You can do a nice high-RPM launch with them. Brake-torques will only get you so far.

>A 1.88 is pretty respectible. The AWD in the T/E/L's (Talon/Eclipse/Laser) can pull 1.6's with the right driver and set-up. I'm normally running 1.8's, though. A 4200 RPM stall should be a lot of fun :) Yeah, baby, YEAH...

> What kind of RPM range does the 455 have? I'm kind of used to the high-revving 4 bangers. I need to swap in a new EPROM in my ECU to up the rev-limiter. My car is still pulling pretty hard at 7500RPM when the limiter kicks in. I'm guessing your HP peaks at a much lower RPM.

Peak torque with my motor should be about 5000 RPM. I shift at about 6200. Pontiac are very torquey motors down low, compared to a BBC or Ford. Even with a balanced and blueprinted bottom end, roller cam, H-beam steel rods, there's really no need to pull over the low 6000s (some Pontiac guys don't even like it that high).

7500 RPM is sure revvin'. Have you experimented at the track to see if shifting that high helps or hurts?
