FiTech EFI system

That's what I did. Now I need to take on the rotor phasing. Before my engine was locked out at 34. Didn't mind it at all. Ran best there.
If I follow fitechs instructions. Can I set my base timing at 20 or 25 and go from there?
My first time phasing a rotor....

You *Can* do anything you want, whether it works or not is the question. Phasing isn't tough, and can be worked out so long as you have adjustable parts.

I know that I was able to use a stock distributor set to 10deg base timing and then tweaked from there - so far, no crossfire issues.
