Ok I got a build for a buddy of mine its a uber budget build.

Its a stock ls6 block with high comp pistons 11.1
ASA cam he likes it lol he has all the supporting mods plus a stall 3600
Thing is Im not sure on heads, His Hp goals is atleast 400 on motor and 500 on the juice hes at 370 hp now ith stock heads and 10.1 compression. Should I suggest 5.3 liter heads with a mild port or ls6 heads. I think the jump in compression will net him over 400 but I looking for some imput. I know boosted motors but this na stuff is boggling imho.

243s for sure done by someone who knows.

If your getting 11:1 with stock size combustion chambers, you do not want the 5.3's small chambers.

Go with the LS6's and get them ported by someone who knows whats up like Predator said and roll on. The motor WILL make more than 400HP.
