I have an 84 Z28 with a 5.7 and stock Rochester. I was wondering what I would need and how difficult it would be to convert it to TPI. I know Ill need computer, wiring harness, manifold, fuel rail, injectors, runners, and all that stuff but like would i need to convert from mechanical fuel pump to an intank pump. this is going to be like a weekend project so i need to know everything before i start so i can get all the materials and tools etc.
