I am getting ready to swap the cam in my motor but not sure if its a good idea. The cam that is in it is a comp cams blower cam that is a hyd. flat tappet. Part number is 11-400-4. Its specs are intake 226, ext 218 at .050.

Valve timing at .006
intake opens 27 btdc closes 69 abdc
exhaust opens 73 bbdc closes 15 atdc
The other cam I have is a custom ground cam that I was using for a nitrous motor. Its a solid roller.
Intake is 242, exhaust 248 at .050
113 lobe and 113 intake centerline
valve timing at .050

The enigne is a 468 twin turbo with 91mm turbos with 1.23 ar. 990 heads and around 8:1 compression. It is intercooled and was a motor setup for speed skiing. I was told it made 1,000 hp on 12lbs of boost. Never dyno'd the motor though. I am in the process of swapping into my jet boat. Should i swap cams, or keep the cam that is in it and up the boost if I need more power?
