Questions for those who switched to EFI...

I've not installed it yet, but I just got my 408 stroker out of the engine shop. I'm installing FAST EZ-EFI with direct port injection. with direct port, the injector literally sprays fuel on top of the intake valve. I'm using a Torker II intake and 42lb injectors. My expectations are good cold starting, excellent all weather drivability, improved reliability, and longer engine life. Ever wonder why newer engines have such improved life? Improved engineering, sure, but you also no longer have a carb gushing fuel into your engine and washing the oil off the cylinder walls. I'm not a carb guy, so spending a extra $$ to have the fuel system rock solid is worth it to me.
