I'll be using a Holly Commander CPU on this motor, with mixed feelings about the unit. I had one already, so that clinched the deal however. There's a GM 7730 (TPI unit) on another Northstar I have and it works really well also. A guy over on the Fiero Forum set that one up for me.
I totally agree with your reasoning on cars. Build what YOU want. the way YOU want it.
