Just depends on the dyno of course, but maybe 420 or so

I was hoping 380-400 and low 12s

I don't see 380-400 hp being a problem at all on most dynos

Ape Man

actually got a set of 799s, but using stock ls1 intake for now... any change to predictions?

oh man lol

Anyways OP i think you were right with your guesses i say 380-390 but since your not using the ls6 its gonna hurt you so i say 370 or so you will feel the torque plus its an lq4 with lower compression . But i rather have 799 installed and then install an ls6 down they road . Easier to swap intakes than heads lol

380-400 is more likely

Basically look at what a cam only ls1 does with similar mods and you will likely make a little more torque but HP will be the same. Most people assume a 6.0l will make more power.

I say 385hp max i dont think hes gonna hit 400. Well we will see....FWIW about 75% of ppl that ask for guess on here never actually come back and post up what they made.
