By the way, If ur doing the stage 2+ heads w/o a cam, u need to find a really good dyno guy who specializes in heads tuning. I say this b/c gash who did these heads first was given dyno gains of 40hp from a shop. Then he went to someone else for a dyno and he only got 10-15hp gained from the heads. SSM says there stage 2+ heads dyno at least 30rwhp, so that's gotta be easily possible with a good dyno but u need to find one first. Gash is now pissed at this little gain so he is going to find a guy to dyno again at either powerhouse or a guy who has experience with dynoing heads real soon. Good Luck but be careful if ur not going heads only not with cam when u dyno.
Oh yeah, I also found out that Vortech superchargers for our cars start at around $2.5k w/o new injectors or a tuner. U can find new injectors for $200 easy and if u have a tuner, all u need to so is install and get it dyno'd. This vortech w/o intercooler is said to put u out 290hp(+80hp) w/the 6psi pulley. And if u bought a 9 or 11psi pulley for it ur gains would be even greater, but I believe if u go 11psi they suggest the intercooled version. Install would probably run $650-$900 and a dyno tune is usually $200. It's really cheap if u want to go FI and the if u buy the 9 psi pulley u should be at 330HP if ur stock, 11psi pulley-355HP if ur stock. Good Luck, with whatever u choose.
