Ok here is a new video from a couple Fridays ago. A bunch of new parts since last post. The previous engine ran well but just not enough to run with 50.5 tractors. So it went under the knife. Now it has a new reverse ground Hackman cam, head swap, MWSC new cast aluminum intake for stock heads, new center exit header, all new fuel system. New front wheels and new hood wrap. It now will turn an honest 10,000 rpm. Has midwests new tech tach on it with recall. this video was a 25 tooth gear over 8000rpm at the end of the pull. Still running race fuel. Had to up grade the pushrods to 3/8 .080 wall with 5/16 ends. Comp Cams springs, ultra pro mag rockers, jesel push rods, comp cams solid roller light weight lifters. It runs now.
