^ i concur.
the LS bottom ends were not designed to be high reving motors. the rod/stroke atio causes the rings to wear alot faster when taken higher than the stock rev limit. the rod bolts are the biggest concern with the LS motor. anytime you upgrade an LS ARP rod bolts are a must.

as far as getting to your comp. ratio, you are gonna have to change out the pistons. try to stay in the 11.5:1-12:1 range anything higher will have to be DE-tuned for pump gas. im personally using weisco 12:1 pistons in my motor, and my last motor had Endyne "roller wave" high comp. pistons.

now be aware your also going to have to upgrade your fuel system to support your horsepower goal. i maxed the stock fuel system out at 190WHP with my current motor.

these builds can get a lil costly when done properly, but you get what you pay for. if you decide to go cheap it will bite you later down the road.

goodluck with your build, its nice to see other people's builds in progress.
