ls3 intake... I seen ls3 intakes in large cubes strockers making big power past 6,800 rpms where the drop off started possibly do to cam limitations, in N-A applications, for what i understand the ls3 flow is very close to that of the ls7...

I'm running a 76 intake basically the same as a 3. The car has a 242,250 dur. cam. The problem with both manifolds is that they peak early around 6200-6400 rpm. Then the power table tops ( just stays flat). My combo drops off around 6800. The manifold and heads stall at this point. I'm shifting at 6400-6600 rpm. The 102 may be a better choice. I plan on trying one soon. i would like to peak at 6500-6800 and make power till 7200 shifting at 7000
