Has anyone heard of V-8 injectors in a 4.3? If so how the hell does it work and is it an easy upgrade? if not what are good injectors and where should I go to get a good price, oh, and will I need a new fuel pump to go with and the run down on that? Thanx for any help what so ever.

I read somewhere on here that it would make the engine run rich, you would probably be better off either cleaning your injectors out or just installing new ones, you WILL notice a little difference:

smoother idling, acceleration, and miles per gallon

not worth the time or money all it does is make it run really rich
i ran 5.7 injectors on my 4.3 TBI and it ran fine. i'm sure it was a little rich but you sure couldnt tell, no smell or smoke from the pipe. no increase in performance either. i installed them a few days before i bolted on my supercharger just to see if they made a difference, they didnt

very easy to do. just disconnect the fuel lines, unbolt the injector pod assembley and swap. make sure not to damage the gasket
