may be a little heavy. if the truck is 4000 lb total which is still a bit heavy, and 55% on the nose, thats 2200 lbs on the front, 1100 per side. ?? thats my base guess for most C10's. The Olds motor is a bit heavier, but only around 50 lbs as far as I know. With the short springs, 1300 lb may be needed. We won't have scales at the So Cal Challenge, but you can call and check our shop for a saturday, most times we have time to scale a car/truck in the a.m.
