Rebuilt 400 sbc. Has zero hours. I have all the paper work and receipts. I had vortec heads put on with the rebuild. Comes with a new holly 670 truck avenger carb. I'm ask for 2500 bucks I put a lot more into it than that. Really good deal! Don't need the motor any more I sold the truck. I'll even throw in the engine stand the motor is sitting on. Thank you for looking.
