Fresh rebuild with only 16,000 miles on it. I had this engine rebuilt for a 78 Chevy C10. When I sold the C10 I put the original 350 back in it because I planned on keeping the 400 for another project car. Ended up buying a newer diesel truck so I have no use for it. Heads are sprung to accommodate lift. Cam has 280 duration and 550 lift. Full aluminum dress up kit. 4 main bolt block. Roller rockers. Is not lobey when idling. Stock engine bottom. Rebuild kit from summit magazine. For more information text or call 8594339601.
