vortec heads???

Fastorgange what did u do about your EGR system on the motor once you did this swap?

well tbi egr systems are different from vortec ones. The old school carb'd motors have egr systems, and the intakes have a spot for egr too. Mostly though ppl remove them, have them tuned out since you'll need a chip made anyways to work with the new stuff, and ditch the whole egr crap, unless you have to pass emissions of course.

yea but the power band range for those open or single planes is way up there too, aint the vortec heads limited rpms?

the power band rating is for carbs , Has no effect EFI.

that just seems weird to me.

I don't know much about FI and tbi and crap though.

What EGR?

EDIT: Should mention, Im running a carb, no need for a EGR or any of that stuff.

if you use the GMPP intake, it has a spot to plumb the EGR in.

There was a LONG discussion on it one time on FSC. consensus was that dual plane are crutches for a carb, not needed for EFI. Its the same reason 99% of the EFI intake out there are single planes.

well idk what your budget is but you could go with the vortec system and then marine intake?
