5.7 Vortec Install Questions
I picked up a 97 5.7 Vortec today for my Blazer, and I've got some questions.
How complicated is the wiring and ECM? Would I need to have the ECM flashed, and do I really need to run 4 O2 sensors? What about VSS? I'm thinking about buying a manifold and putting my Quadrajet and HEI on it to make it simpler. Any thoughts? |
