I had to hurry to get the engine switched in the Jeep. I put this engine in just for mud bogs, as it’s a fairly well built small block chevy. It’s a .030″ 400 full roller with 11.5 to 1 compression. It really comes alive over 4,000 RPM. It made enough power to take 1st place in the 35″ tire class and 3rd place (I was less than a foot from 1st place) in the 40″ tire class. Making over $300 in the process made it worthwhile.
First picture is just before the start of the 40″ tire run.
