I'm an oldtime dirt track race engine builder who likes to tinker with oddball modifications that other people say are impossible. Like Hank Williams Jr. says, "It's a family tradition!" Dad was a master mechanic whose chosen obsession was modifying flathead Ford V8's in the late 1940's and early 50's, and I grew up around a racing shop in Nashville Tennessee. Yes, I build engines, but not commercially. Drop me a private message and we can discuss what's involved in building your engine, either stock or modified.
