All Mopar \6 Fuel Injection?

It would be easier to install a 4 bbl intake and a TBI system like Accel or Holley Pro-jection. The Accel TBI uses standard MPFI injectors, so you can swap to smaller ones to match a slant's fuel needs. Motorvation and others have a similar (same?) TBI. After-market ECU's don't usually require a crank sensor, just a coil connection for rpm, TPS, and better ones add MAP and IAT sensors (not Pro-jection). MAF is nice and adaptable, but harder to package and not really necessary.

That said, I am planning a custom MPFI for my slant, but another year.
