Good thing I gave the big truck another chance before going to the scrap yard. Took the big tires off (33X18.5X15 M/T ET's) and put the tires off the little truck (29X11X15 Hoosiers) on the big truck. Friday night first pass had a 1.71 60' and ran a 7.96. Second pass had a 1.71 60' and ran a 7.92. It ran in the 7's and I'm happy. Think it would probably run some mid 7's at sea level and with a little tuning but don't want to go the roll bar route with the big truck so have to stay at 7.50 or above.
