    Cadillac 500 (EFI swap & tbi swap) and crossfire troubles

    First post: I joined because of several upcoming projects. A friend might give me an 84 Vette that has crossfire troubles and I'm going to be looking for injection swaps for two Caddy 500's.
    If I get the 84 Vette, I'm going to try fixing and driving it, but it's main purpose is to work out the bugs for a Caddy 500 swap. I'll either mod the crossfire or swap on a standalone tbi system.
    The other 500 injection swap will be for a stroker build destined for a nice 91 Vette. I don't know if I want to chip the Vette and modify it's batch fire system or swap in sequential injection. I like the injection of the Caddy 4.9's and they are plentiful in the bone yards.
    My name is Cody. Looking forward to our future interactions.

    Many options for EFI conversions with either Aftermarket or Factory systems.

    The Factory 16197427 computer could be a "one size fits all" computer for either a TBI system or a batch fire Port Fuel Injection like the Chevy TPI (aka MPFI). The added bonus of the the 16197427 has the ability to control either a 4L60E or 4L80E. The use of a Vehicle Speed Sensor is strongly recommend with the 16197427.
