racecar - do you think the TSP 233/239 would be too small in a 383 stroker for road racing? My preference is to have the cam kick in at 1900 RPMs and peak at 6400 RPMs. What RPM does your torque begin to drop off? Mine appears to be dropping at 4800 RPMs.

My 233/239 torque begins to drop at 4800 also. HP curve flattens out at about 6000. I thought that my hp curve was flat until I looked at yours again. You have a good flat curve. I am looking at my G-Tech runs and the HP flattens a little earlier than yours, and stays flat to 6500, that 's as far as I have run it. I have a 346, so the 233/239 in your 383 it may peak even lower. Looking at the 2 curves, they are really close. I will have some real dyno numbers in a few weeks, will post then.
