Question for you, did you do your cam install? I bought a cam with close specs to yours, was wondering where to buy a delete kit (complete hopefully). I keep thinking texas-speed but the sprocket isn't included, did you just use a ls3 3-bolt sprocket?
G8RAM who runs almost identical cam, has ported heads, tune, ect. this was before the intake swap but dyno'd 415HP before the run. Thought it would interest you since you have close to the same combination.
