Your question was directed at Blaine but I'll jump in and offer my 2 cents. The top of the line Holley ECU is the Dominator. That's the one I'm using because I have an I.R. intake and can take advantage of the Dominator's features. If you're using a single throttle body based intake, the Holley HP ECU works great.
Autotrend EFI in Northern California is my Holley dealer and fuel injection Guru! They can even supply a Pantera specific EFI harness for both the HP and the Dominator.
