I'm just curious if somthing is wrong with the pump or if it isn't working well with the rest of my setup. I'm going to talk with the folks at edelbrock next week and hopefully they make it right. or at least tell me what the problem is so I can make it work correctly. It is advertised to help equalize flow through each side of the engine but this one ain't doin' it. As far as the wrapped headers...I havn't run it enough to know if I like it or not. the fenders aren't getting as hot and that was one of the goals. All the sheet metal around the engine was getting very hot before so I'm trying to eliminate some of that.
