I just pulled this from a drag car I bought. I was told when I bought the car the motor was just rebuilt, which I belive because the car was unfinished and was noway it could have been ran in the car. We finished the car and have put 6 passes on the motor and relized its just not enough motor for us. It runs great doesnt leak oil, starts right up. I dont know anything about the internals of the engine. I was told it was built on the specs of the 400hp crate motor. It ran decent in our car but nothing spectacular. It will come with everything in the pics except altenator and electric water pump. Asking $800 May do some trading on big block parts.
