I got the motor From our local supplier of 5.3 and 6.0s. I usually get them for the turbo guys or budget guys of mine they will run them as is or they will tear them down for a forged bottom end or 408. We are located in downtown KCMO it's a complete motor minus serp system it does have water pump and belt ten and crank pulley... Pulled from a 2000 silverado 2500.
