I have a 86 Astro that im about to replace the V6 with a Mid 90s V8. The V8 has Vortec heads on it. I still want to use a TBI setup, but not sure if im going to run into problems with the EGR, or any other wiring problems? Has anyone else used this configuration before? Can i still use my stock ECM? And what distributor from a V8 can i use? What will i need to rewire....
