Howdy yall. Names Chris, I got a 1979 Trans am with a 403 and a 1979 Z28 thats gittin a stroker motor. Neither run and tha T/A is rusted to hell. Yall think i should pull tha 403 olds out and build it up to drop in a car one day, or would that be too much trouble. Its rated at 185 Hp and 320 lbs of torque. Is tha 403 a small block or a big block?
