dyno #s for vortec heads hsr lt4 cam

I was wondering if anybody has a 350 l98 with stock vortec heads a lt4 hot cam with 1.6 roller rockers and a holley stealth ram(24lb injectors) and what kind of dyno numbers are they running? I am in the process of installing now and was curious on what to expect.

If your your running about .040 piston to head clearance I would expect about 400hp

they say that cam with LT4 intake/heads will make over 425hp. not sure if thats true or not but the LT4 conversion says 425+.

i'd say your gonna make near 400crank
