I read through the H/gas rules, seems like a tuff class for a flathead. If I'm reading it correctly they include OHV I6 and 4 cyl (about anything 67 or earlier including VW). A Chevy OHV 6 can put out some power! When we were racing our B/altered (mid 60s) there was a flathead altered (D if I remember correctly) that ran local. I6 OHV were allowed in the same class and it was very hard for a flathead to run with them. We also (later) ran a 2300cc 4cyl overhead cam engine. It would run 9000 rpm easy and I think around 230 hp. Again, not easy with a NA flathead. Tuff to compete with more modern engine designs.
