Was wondering what kind of HP you think i am making with the folllowing mods:

PP S2 heads, TR 224 114 cam, FLP LT headers with Loudmouth CB.
LS6 intake, LS6 oil pump, Hypertech thermostat, Lid, etc. LS1 speed dyno tune.

The car has a stock 3.42 (M6).......what do you think it could run on street tires?

Thanks!
