Fuel Injection add on??

I could be wrong but in my opinion the HP stuff is just about the most configurable and "growable." You can convert it later to multiport, and it "does" all sorts of extra stuff.

Mine is a mish-mash. I started out buying a used Holley Commander 950 TBI 4bbl setup, and later bought the later HP ECU and harness for it.

I nearly went with Megasquirt, and may yet if I live long enough "to play" LOL

Still others have hacked up GM computers over at "The Binder Planet" and built their own, using re-burned chips, as the GM chips are socketed.
