1980 3.0 with Elgin "SC Sport" grind cams(similar to the ones being discussed) - also EFI, but stock intake and EDIS ignition. Stock exhaust with hollowed out cat. This is at the wheels, so a bit better than stock which is BHP. Also note how flat and wide the peak torque is. Don't have the "before" picture, but you can really feel it once it gets to 3500 +. Can't tell if there is any low-end loss.
