Questions for those who switched to EFI...

I have had a Holley Projection on my 65 Newport 383 since 1996. It is a bit quirky, but still better than the carb was. I swapped to the later Delphi throttle body, but it seems those injectors are a bit too small. Still, I don't recommend it due to cost/benefit.

I have a Commander 950 I will try later on the Newport, Dart, and/or Valiant. It is much better with more sensors (manifold pressure, intake temperature), a programmable map, plus can control spark timing via GM HEI module, plus a wideband O2 add-on. I also have another ECU without harness, so maybe 2 cars eventually. I hope someday to adapt a Magnum MPFI manifold to the SB. Some use Megasquirt, but it is a lot more roll-your-own.
