The 5.3 (2005) I bought for my truck has square rails, the one I got for free for my brothers truck (03 or 04) has the round rails, any difference? One better than the other?

Good deal, I had no idea it was a flex fuel motor. So bigger injectors too then

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
Just make sure you get the fuel setup for returnless since you are sporting an 05 setup.
