There are a lot of variables involved in a build like this so its hard to quote what it will make. The blower should be able to get you to 600rwhp assuming everthing else in the setup works out. You also should consider upgrading to a dual valve spring package over the PAC1218s for this particular setup.

thaks Aaron did query the pacs when I bought the engine seller claims they were speced with the cam

Aaron at SDPC

Yes the PAC 1218s are rated to .600 lift so just make sure whoever sold you the package is correct on the camshaft specs as well. I believe you listed the intake valve lift at .610. Stepping up to a dual .650/.660 dual spring setup is what I would recommend.

yeah making 620 wheel with a t56 and 9inch . Mines making the 620 at 6500 rpms with stock heads and cam. ls6 intake , pushrods and springs from btr. Making 11-12 lbs on 93 with water meth . So yes you can make it out of a p1sc-1 .

There is no reason why you can't get 600 rwhp with a P-1SC, it just takes the right cam and heads, and you should get there. Bob
