I agree, years ago I abandoned my entire ECM and went to an Edelbrock 650 CFM carb and changed my ignition system to an HEI vacuum advance. In hindsight, it wasn't a great move. The E4ME Q-jets aren't as bad as many people think. I have done a 305-350 engine swap on my '84. I took a 4-bolt main 350 out of a 1992 Chevy 2500 and transplanted it into the Caprice. I used the TBI and all. It's great actually to have my '84 fuel injected now. I did some mild modifications to the TBI unit and upgraded the fuel pressure regulator to keep it from falling on its face at WOT like they are know for. The swap wasn't bad, and took minimal modifications to get the TBI computer to work properly in a car that was built 8 years prior. I'll soon be posting a thread with pics and updates as I haven't been on here in quite some time.
