Re: confused

For the 3400/3100 heads, yes, piston need to be changed. If you can tune for the 11.5:1 compression, 3500 head will work with Camaro pistons.

ok thanks and from what i have read i would need to go MS to tune it for that right, and i would need the 3500 intake withe the 3400 plainum and throttle body. i hope i got that right.

Re: confused

Intake has to match the heads, but the UIM's are interchangable, correct.

The 3500 UIM doesn't fit under the cowl unless you modify the brake booster port.
