Timely question since I made a junkyard run last Friday and saw interesting Mopar parts I hadn't seen before. I saw the small-block TBI intake in a Dodge van (recall). The TBI looked similar to the Holley Pro-jection on my 383, with the older round-top injector connectors (injectors gone). It had the same 3 bolt mount, so I expect a Pro-jection TBI would bolt up. My Pro-jection system has always been quirky, needing regular knob tweaks even with O2 feedback. The later smaller ECU seems worse than the earlier long box. The quirks are probably due to lack of sensors, using only throttle position and rpm. I read that the current system adds manifold pressure and inlet air temperature (>$1000). I think the Mopar TBI would work better with an after-market ECU like the Holley Commander 950 or Megasquirt.
