get some hughes #1110 springs and retainers, reuse the stock roller lifters, and get the stock cam reground by Bullet Cams, to something with about 212-216 @.050 duration and .315-.330 lobe lift (I'd go with their HR270/330 lobe) for both intake and exhaust

magnum air gap, 1 5/8" headers, and a 650-750cfm carb and you should be in the high 12's no problem. probably can get by with less gear...
