MPG change w/ these mods?
Will porting my heads rape me at the pump? What about cams? What could I get that wouldnt change anything under normal driving conditions?
Also... what will I notice w/ each of the following?
Moroso CAI
No Cats
Hooker LTs (coated)
bigger Y pipe
Thanks.

If you can keep your foot out of it cars with cams and exhaust and ported heads can still get decent mileage but expect a couple of MPG drop. Small cams with the proper tunning can actualy increse your milage because they make the engine more efficent.

Honestly, porting the heads and intalling a new cam shouldn't change the gas mileage TOO much (maybe 3-5 mpg less), unless you're really romping on it all the time or if you have an automatic with a big stall (leaving a dead stop at 3000 rpm+ every time and shifting higher under partial throttle)
The bolt-on mods that you mentioned shouldn't affect gas mileage.

3-5 is a lot! That's at least 45 miles per tank. Can anyone that's done this confirm it?
I'm aiming for low 12s on the street while still getting 17-20mpg in the city (what I'm getting now).
These LS1 SSs sure look tempting!

anything exhaust related will help you... i think CAI will actually hurt mpg a little since more air needs more fuel. same applies to heads... more air in needs more fuel so youll lose some again. and yeah a cam will definitely decrease fuel economy.
