  i was wondering if anyone has messed with the plastic intake port efi from c1999 gm vortec engines.  i have a sbc with vortec heads and realized that i have the intake, harness, and ecm from a 99 delivery box van.  do you suppose that would be worth replacing the holley 750/performer rpm setup ive got?  efi is what i want, but i was told by someone i dont necessarily trust that these plastic intakes arent worth much.  what do you guys think?
