The EFI allowed ME to put enough in it when its cold that it would actually stay running.....AND not be loaded up when it its warm. I could also INFINITELY adjust the AFR to the cylinders a little wet (not pig RICH) while "cruising" at low throttle.

Something else for the OP.....most stuff has been mentioned; however, one other point to make about EFI is your charging system MUST BE AWESOME!! rock solid voltage is a MUST for efi to perform correctly. So if you have NOT upgraded to at least a cs130 or 144.....this would be the time.

I've heard that before on the charging system deal but never experienced any issues myself. Both cars still have bone stock charging systems with external voltage regulators with stock output alternators, and they both have been flawless in that department for over a year now using the Holley Super Sniper Stealth units.
But I'm guessing it has a lot to do with wiring, isolating everything properly and having good grounds.
