Replacing FAST EFI on HP 383, with what?

FAST has the worse service techs I've ever tried to talk to. This is a common complaint on blogs. My problem with FAST is inconsistency in driving conditions. Seems to take the computer a long time to adjust. Any changes you make effects other driving conditions. Maybe I am not giving it a chance. Maybe the race mechanic I have taken it to can set it up. If so, I'll run it for awhile, but remember, I am old school and I understand carbs. I don't like wiring I am not familiar with. And, it looks like crap sitting on top of the machine. Not a real good answer, I just like carbs more.
I am most interested in matching the convertor to the camshaft. I am waiting for a recommendation and affirmation on the choice of cams to match up with the Edelbrock Al heads. I like mid range acceleration and like a 373, but will keep the 355 in the rear end for now. Would you recommend a TC and with what 727 to go with it? Thanks.
I have never had any problem w/ the service techs at fast, contrary, it`s been among the best I`ve dealt with! They are busy, but have called me back when I couldn`t get ahold of them. I`m no wiring expert by any means, but their directions and a "little" common sense worked for me. I only have about 350 miles on my fast 2.0, but it has already smoothed out and running fine. I have changed the fuel ratio, and timing some tho. Pricy, but comes w/ everything, no need to go order other parts, or scrape up fuel pumps , or somebody elses regulators and such ! Very nice to tune, in the drivers seat ! Have heard that a lot of systems need about 500 miles on them to clean up .
