As the completion of my motor gets ever so close what kind of power do you guys think it will put out??? I will be running a medium shot of nitrous on this motor but im interested in the n/a potential. Thanks in advance

Sounds like one bad azz combo. I am not familiar w/those heads, but if they are up to the job, I'm guessing over 600rwhp. With that much compression, is there a reason you didn't use one of those Pat G LSL lobes? Those cams seem so hot right now.

I say somewhere close to 550HP. Good luck with your build!

I got the cam for cheap from a local guy off ls1tech...it was what i was looking for... ...I should have flow #s on the heads in a week or two, according to my machinist, then the motor goes in.

Please post in the dyno section after you have results.

I made 540/495rw with that cam on a 114, a point less compression and 90/90 with TFS 235's. I would guess you could get 550/510rw with the extra compression but your intake is going to kill you. Your headers are too small as well. I think the SLP will hurt also. Big cube motors need straight 3" all the way out. Realistic numbers for your current combo with the gears is probably 525/500rw. Good luck with it. I went with one of those new fandangled Pat G cams and I am making 575/530rw now. I never did the EWP or 3" exhaust.

p.s. With your DCR being so high you will proabably only be able to get about 22* of timing in there on pump. I am assuming this is going to be a race gas motor. If so I would bump the cam way up and have at it.

Thanks for the replies guys....i was really hoping you were going to shed some light Pray as your combo is pretty similar...i would go open header but its just too loud inside the car, maybe strictly for dyno numbers ill take the slp off. This will be a race gas or pump/race gas mix motor as i dont think the 91octane available will cut it. The only reason im running the ls6 intake is to make the fast fan boys mad hahaha...if im not happy with the hp results i will switch over to a vic jr carb setup i think a fast is just splitting hairs when running a power adder.
