can you pass emmissions with c306,
also what would you gain on a lt1 with stock heads but 1.6 rockers?

thanks,

I wouldnt recommend the cc306 with stock heads even if you didnt have to pass emissions.

cc306 does fairly well with stock heads. im putting it in my stock head car soon. another guy around here is also running it with stock heads. his car runs very strong, traps somewhere in the 113-115 mph range. as for passing emissions, i wouldnt count on it, but who knows.

Don't think you'll get that thru emmissions but then again each state/country has it's own levels for emmissons.

396, CC306, and ported LT1 heads with full emmisions will make it through an IM240 test with a proper tune and good cats.

So I don't see why a stock 350 with stock heads would have any problems. Just don't plan on going through with a stock program on the PCM.
