It's a 226/228 .570/.571 113lsa+1 i've got all the free mods, Ported TB, and UD Crank Pulley? It's an 02 w/M6 mid length headders (lowered) ORYP (stock heads). So with the cam alone, what can i expect? Also i plan on getting some S2 Heads in March, which ones will help this out?

Thanks,
Kenny

 

with a good tune i'd say in the 370-380 range.
