i got my "college edjamacation" in EFI when my best friend and i installed a late model LT1 in his 55 chevy belair.
to say that was a STEEP learning curve, would be an understatement for sure !
one thing that helped tremendously, was when i fished a complete cadillac FSM out of the dumpster at the local chevy dealership.
that provided the wiring diagrams necessary to get the car running, as well as the many trouble shooting methods to find out where we screwed up.
that car turned out to be a GREAT running [and driving] car, and a local fellow just HAD to have it, so after offering a STUPENDOUSLY ridiculous offer, the car was his.
since then, we have built several other vehicles for local guys, but none has been EFI equipped.
