Default LS3 dyno estimate

I'm wrapping up the build on 6.2 build with l92 heads. The engine is bored to 4.070, with Mahle 2cc dome pistons and lunatti rods on a stock crank.

The heads have been shaved .010 and these are the specs on the cam from tsp 227/234 .629"/.615" 113LSA +3. I'm running a stock ls3 intake with a stock ls2 throttle body. The transmission is a gto t56 with an ls7 clutch with a ford 9 inch with 3.55 gears. This is going into my project 71 Chevelle son it'll be awhile before I get to actual dyno.

What do you guys think it'll make.

What sort of exhaust? Stock exhaust, long tube headers or shorty headers?

No reason it should not be up in the 480+ area

Thanks for the responses, I'll be happy with 440rwhp and 420trq, but more is always better. It'll be a couple of months but after I get it to the dyno I'll post the results.

No not yet, engine is in car running but I'm at least two months away from getting the car road worthy.
