I have a smog prob here in cali and need to do something different with my carb setup. I have a nicley built up 406 and I want to swap in FI. I am thinking AFR or world product heads with the vortec intake pattern and get a 96' and later FI system. I got a quote for $350 for the ecm, intake and everything on the intake like the throttle body, injectors,etc. He told me to have a wiring harness made to make it easier. I am looking for around 50 to 75 more HP over my current stock heads and carb with a better power curve. What did it take some of you guys to put the vortec injection on a non vortec motor with vortec bolt pattern heads? What did it cost when finished and running? Performance? Pics? thanks!
