Well, for those who are interested.....Went back to the Creek after finishing my rear suspension today and first run ran 14.1 @ 99.9 mph. Had three more runs 2 x 14.2 and a 14.3 (muffed a gearchange)
The first run was in daylight and, therefore my headlights were off. The three other runs were during darkness. Mph during the three night runs was down about 1.5 mph average. I assume this is from alternator load???
Ran two 2.1 60's which was good and means my rear suspension theories worked
