Finally got my truck back with the edelbrock headers installed. Well I feel it... I know that's not very scientific but my commuter car is a 700 HP corvette so I think my senses are pretty good.
I live and drive in an area with many hills so it wasn't very hard to determine that it picked up low end torque. More get up and go at less RPM.
I have 200 miles since picking it up yesterday and I resetted the average MPG when I got it. So far it shows a .9 MPG improvement with the headers. Same driving habit, same roads.
Time will tell but they are easily worth the money IMHO.
