I'm building an LQ4. Boring it out to 6.2, using stock ls3 pistons, stock rods, stock crank, L92 heads not milled, LS3 intake, long tube headers, lingenfelter gt2-3 cam duration @ .50 207/220 lift .571"/.578". I can't get the engine back until the shop balances the crank, and I need the flywheel, but I have not bought a clutch kit, with flywheel yet because I don't know what kind of horse power the clutch need to handle. I'd like to go with the level 1 monster clutch for about 450 rwhp, but I'm just not sure.

Why such a small cam? If your going through the hassle of machining and building a proper short block then theres a LOT more to be had with a better cam selection with little to no compromise in drive ability. Moster stage 1 clutch? Blah forget it man run the LS7 clutch and thank me later

Either that or step up to a level 3 or something that can take a beating
