I've been wanting to upgrade my 81 Z to fuel injection. Can't afford to go with a LS swap. A friend of mine gave me a 99 Tahoe with a 5.7 vortec,4l60e,wiring harness & ECM,which I think will be a dollar down swap. I mean I already have the major component's,I can do the work myself. What are the opinions of doing this swap? I know it's not the most desirable swap but I won't have to starve just to get fuel injection. Please give me some feedback!
