I'm assuming you have heard nothing about a future NQS class the OHV single. I guess there's no interest besides a few people. And I'm sure there's a few tractors across America that have a OHV conversion on their flathead. Like the Odd Couple twin engine tractor that runs in OSS. But he only needs one engine running lol Well I was kinda hoping for Interest. I think NQS should add classes along with technology. Now days most engines are OHV. Hardly any flat heads anymore. Mostly OHV twin or Singles!
