OK, that's different. The reason I didn't include the '68's, but only the '69-'72, is because I don't like the bumper and taillight arrangement on the '68's. It's just a personal preference thing.
I wonder if the hp difference in the '68 & '69 has anything to do with the size of the valves, in the #48 heads ? Or did somebody just request that the '68 factor be lower ?
