Default Cheap 403 build.. opinions

i got a 02 SS thats been sitting for almost 2 years now and im sick of letting it collect dust i planned on using some better parts for the motor build but im just gonna go with what i got since i already have the short block done i can do heads/intake later on once i get more money heres my set up so far:

-callies 403 stroker
-6.0 iron block bored .005
-callies crank
-callies prostar rods
-SRP flattop pistons 11.2:1
-TICK PERFORMANCE polluter cam (242/242 610/612) 112LSA
-home port to match gasket stock LS1 241 heads milled .020
-LS6 intake
-bigger injectors (not sure what size yet) little help would be appreciated
-LS7 lifters

i was wanting and still am later down the road to do an LS3 heads/intake combo but gonna go with this for now just to get her back on the road. i know these heads and intake are gonna cork it pretty good but oh well haha what kinda power do u guys think ill be able to put down with the setup above? ive read a few guys getting around 475-490RWHP on a similar setup which would be AWESOME!!

also this is a 6spd car with a junk 10 bolt in it which wont last long i know like i said just wanting to get her on the road and cruise will get at least a 12bolt very soon.

fire way fellas THANKS!!

High 400s seems to be with a fast and at least 243 heads. If I were to guess, yours would put down closer to 450 as it sits.
