Okay say i went to buy a 2010 camaro ss, then i wanted to get its ultimate power so i got it bored got it cammed got the heads intake polished got it headers got it a cai basically doing eveything to the engine to give it hp without adding a supercharger, with the ls3, how much hp gains am i looking at? And maybe a price of all of the mods?

 

Hard to say without more details, but still a guess. My question is, being that you done all the things you said you did, why are you asking about the price? I doubt anyone will do all that work without quoting you price. I really question the part of boring an engine with sleeved cylinders.

 

with the money it sounds like you already spent you should have gone SC or Turbo to start!!

 

all motor LS based cars are running in the low 8s at this point. This is an all out race car with a 50k+ dollar engine. To get the most out of what you have, realistically with a gutted race car with worked LS3 heads on motor, you might be able to get it into the VERY HIGH 9s? But thats with a lot of work and some serious cash into suspension, getting the bolt in 9 inch housing they make for IRS etc etc etc
