As I posted in my intro thread, I recently bought this 1983 Olds Cutlass Supreme 4 door. 75k miles, 231 c.i. V6 GM power plant, 3 speed automatic.

Current motor has rod knock and will be coming out soon.

Plan: 5.3L LS truck motor, keep AC (100% needed in FL), turbo + goodies
Goal: 500 whp sleeper to drive on weekends, drag race once in a while, eventually do the Power Tour or Drag Week.

Taking the motor apart to inspect. So far, so good. Has some nasty iron sludge from straight water in the motor, but I can fix that.

Little more progress:

Pulling the engine a part, oil pick up looks fine but sludge in the oil pan.
