Dominator EFI ECU and distributor

Here is a link to our fitech page, but they specialize in tbi ( which I think is perfect for a slant six)
FiTech Fuel Injection
but...if mpfi if your goal, then we are back to the holley hp, which is still cheaper than the dominators.
HP EFI ECU Holley Performance 554-113 - Pace Performance Parts
At the worst your could use a crank trigger. I dont know off the top of my head if a distributor can function on these as pickup and distribution. When im back in the office I can look up a holley 4150 throttle body (air only, no fuel) and the hp and harness and such. If thats the route you want to go. You may have to have a fuel rail custom made.. But I can get any kind if injector you need. Let me know. Let me know more, and I will touch base tues. Glad to help!
