700hp With A 408 Possible?
Making that kind of power is going to require about $6500 in heads and intake. Solid roller. so another $1200 in cam and lifters. 8000 rpm Nothing gets cheap about it. Trust me I am looking at $5000 out of pocket to sell my stuff and put a set of full tilt mast heads that will make 760-770

i got 724HP 602 ft. lb torque out of 425 cu. in. LS2 block. Eagle rotator. LS3 heads ported by bowers out of Ft. Collins. Holley tall efi intake, 92mm intake. I think we used 45# injectors. 91 Octane at 3800 ft. elevation. Gibbs oil. lots of dyno time. Lots of ZOTARS $$$$$$ The holley tall efi intake is a tight SOB in a fourth gen.

So exactly what heads would i be looking at to do this or get close? Whats a ballpark on cam specs? And how do u determine what is a safe max rpm, is the valve train the limiting factor or do u have to take into account things like bearings and length of the stroke?
