new dyno numbers....some questions
ls6 manifold, all free mods, mac mid lenght headers, cheap no name muffler, home ported heads, custom comp cam(not sure on the specs)
well what i wanted to know was how much is 5 degrees of knock from 3800 rpm up and only 26 degrees of timming hurting my numbers. we did later fix the problem, but i didnt have the extra 100 dollars to go on the dyno again.
my best run was when we only took it up to 6000 rpm.
438rwhp ,404rwtq (corrected)
