Ignition Help

NGK GAPPED AT 32. I checked all my plugs and just #1 was really black so I switched cylinders and will recheck that. As far as traction its a 72 swinger with glass hood, fenders,bumpers and valance. 90/10 up front, slant 6 torsion bars, out back 8.75, 3.55 gears, pinion snubber, inset springs, 002,003 springs, 315/60/15 mt drag radials. Full cage and sub frame connectors. Not sure waht to do nest on that. Lost last night to a big block 87 stang cuz he kept pullin me out the hole. Gotta hate that.
