What kinda power will this 408 make ?

Its a 4'Mopar ( Scat ) crank,K-1 H-beam rods, CP pistons ( 1.5,1.5,3mm ring package with napier 2nd ring ), comp big mutha thumper hydraulic cam ( .243 / .257 @ .050, .507 / .494 lift , int centerline 102 ), Crane lifters, Billet timing set, Charlies Pan ( no kickout or anything fancy ), BHJ balancer, RHS heads with 2.02 valves and otherwise out of the box, Harland Sharp 1.6 rockers, Victor 340 intake, 750 Holley dp. Compression will be around 10.2 to 1. 1 5/8 headers.
I'm shooting for 500 HP and 525 TQ.

I know several folks have built these, just curious what ya'll think it will make . We'll dyno it when its done.

Thanks a bunch.

470HP. Don't think you can make 500 with those heads - out of the box.

I think you CAN hit the 500 number with those heads with a 2.02 and a good bowl blend. Brian at IMM did it; although it took a 950 carb and a healthier camshaft.

I think, as you describe it, depending on air quality...you're around 460-47--ish HP.

Are going to get on the pump and let us know? Please keep us posted if you do!
