When we ran the Furd 2.3L. OHC 4 cylinder engines in the "Mini-Stock" class at a 1/4 mile dirt track, somebody was selling a cam belt sprocket with about 10 keyway slots in it. Some of those little screamers would run 9K RPM or more.

I'm thinking about setting up one of those modified stovebolt engines on a trailer with my water brake dyno hooked up, and making the rounds of a few swap meets and car shows with it.
