Please Note: In the video I said valve lift is 1.08 inches for the intakes and 0.968 for the exhausts. This was a mistake. The correct valve lift numbers are 0.720 and 0.645. Thanks!
Jami Stoen and Stoen Racing Engines specializes in the USMTS Dirt Modified race engines, and he was kind enough to let us in on the process. What's most interesting here is how you build an engine capable of winning races around the very limited intake and exhaust ports of the spec heads mandated by the rules. Also, special thanks to World Products and Erson -- [ Ссылка ] -- who were a big part of this build.
