You can get a version of Edelbrocks for almost any popular engine family.

Installation isn't that hard depending on how the computer is set up. A friend of mine installed a Holly set up (before they were bought out and this line was discontinued) on his '79 Bronce with a 351W. Had it running in a day. It was set up like a 4 V Carb, but with injectors. The computer on that model didn't require a laptop to program, but since then most systems are more precise.

Because of the engine I'm using in my Studebaker (6.0L), I'm using the OEM ECU.
