Who has added EFI to 396 BB

[MARKDTN]

Since your engine is relatively stock, I would do a stock GM 454 TBI system. Should be available pretty cheap. Same computer and harness as a Small-block system, but different PROM and injectors in the throttle body. If you do that, you can buy parts at any parts store in the country. Should be able to find this in a pick-a-part yard. Need complete intake with sensors, computer, and wiring harness. Add an oxygen sensor bung and a fuel pump. These do not use VATS and are OBD1 so not a bunch of extra stuff to worry about. Could use a fuel tank from a TBI S10 Blazer with pump if you want the tank out of the cab or just add an external pump to the in-cab tank.
