I've asked questions about this and saw some good build threads. I also keep getting questions on why would I ever want to do that. Is there anyone who has done this and driven it for a while and been happy with it?

How about the mpfi upgrade? I'm rebuilding the engine and beefing up the heads, new cam, and flat top Pistons, so I'm making the horsepower if the mpfi can take it. This ain't a daily driver, more of a projectI believe it's typically done when someone can't diagnose the factory EFI. In rarer cases the owner has made modifications outside the capability of the factory EFI. It doesn't take much to outstrip the capabilities of the TBI, but the Vortec has a lot more overhead for performance.
My TBI couldn't handle my cam, so instead of a carb swap I went with a Holley Sniper. The same engine ran fine in a Vortec truck.
