So looking at the torque curve comparsion....it must be a combo of the cams-larger valves and probably shorter ITB runners that shifted the torque curve so much higher....

So what size diameter ITB and how long of a runner? My guess is 52mm+ and maybe 6 inches

Hi Brian.
My dyno chart made Louie's results even more impressive because I have 30 more cubic inches, more cam etc but only made 30+ more hp.

I had no idea I was missing low end torque. Driving the car on the street isn't very practical because putting your foot into it at any speed or rpm range induces wheelspin, at 5200 it then shoots towards the redline quickly.

The throttles are 54mm. The intake track length is about 9". The ports are bigger too.

BTW, how is your car? I heard you got some nice results from some practical mods.
