    Question Another HP/TQ Guess!!

    I am ordering a Texas speed 370ci iron short block, TSP torquer V. 2 cam, PRC LS6 heads(show to outflow the AFR's), 36 lb FAST injectors. Already have all the bolt ons: MAC headers, ORY, borla catback, MTI lid, smooth bellows, LS6 intake, underdrive pullies, ported TB, and getting a custom dyno tune(HP tuners). What kind of #'s you guys thinking? Hoping for 420-450 RWHP and a decent amount of torque from the torquer v2 camshaft.

    how much is it for those heads... with that block you should be able to run L92 heads which outflow AFRs without any machine work whatsoever so they have awesome potential and are relatively cheap. as for your number I would think more along the lines of 450-460 pretty easily. AFRs show awesome dyno numbers with any cam and if these heads will outflow them with that cam you should be sitting pretty nice.
