I agree with Intense.
My old Bobcat wagon had the same heads untouched, 650 Holley, .498/280 hyd cam, flat top TRWs, 2800 stall C-4, 3.89 gear and ran 12.50s @ 106 no bottle. It had 235/60/14 M&H street stickies and hooked decent, 1.75-1.85 60 ft. times. Probably could have gone faster if I tuned it a little more but WTH, it was a bracket racer. Oh yeah, it weighed 2840 lbs with driver. Have been told that those times at that weight translates into 291 HP at the wheels.
I suspect that with sucky street tires, stock '93 weight and roughly the same HP as my old combo you will run low to mid 13's.
It's all about power to weight, PLUS traction! :Track: and be sure!
