I have everything you need to convert to EFI, I have the manifold, a complete uncut engine wiring harness, the ditributor, and ignitor, the only thing you will need is a knock sensor and an o2 sensor.
I planned on using this on my own truck, however after disassembly, I found out that I have an older style head in my 85 pickup, so it won't work.
These parts are from a later generation EFI, 1993 year truck.
$375 or best, located in Denver
