By built up 3800, here is what was done to the engine. Has a Comp Cam VS Cam .507 lift on intake .512 intake on exhaust Lightly ported heads that were milled 3 angle valve job 1 3/4 inch ceramic coated headers 3 inch down pipe LS7 lifters from a Corvette Full roller rocker arms Ported and machined intake manifold, supercharger, and, throttle body Trans shift with increased line pressure
With all this done to the engine, the car still behaves like a normal car until you get on it, then it screams.
Also, I should mention there is a 1 1/2 inch tear in the driver's seat, covered by the seat belt.
