Post 11 second small block combos

as far as the rpm's go...my car, I no longer have, was originally 5.38 geared dana 60
I had 31x13 mickeys ladderbars, floaters, and SS springs. 1.52 60 ft with the best ever of 1.499. 7.016 1/8 and 11.21 1/4 119.01 mph. big tires take away some gearing....
crossed the stripe at 7000 rpm....
the 1/4 mile times went south when I switched to 4.88, as so with the 1/8 and 60 ft. I then switched to 5.57 and ran 1/8 only 7.02 3 times in a row,
yes back to back to back......
