Howdy all.... Great Site, I can learn a lot here!
1994 GMC 1500 RC / SS; 5.7L TBI; Air Intake (K&N) and Ignition ("D.U.I" 8-pin Dyna Mod and external Coil. "Accel" Cap, Rotor & 8mm wire set) upgrades only.
I have pondered notions ranging from buying a late model Porsche 911 to restoring a '70 Chevelle SS 454 (actually bought a used LS5 long block!) to incremental performance upgrades to my existing (paid for) Truck.
The latter sits best w/ my personality, so MPFI, in one of the hundreds of options / combinations available to pursue, is the focus of my attention.
Take care, Larry
