Yep, cams gotta be driven by something, no matter where they're situated. Chains, belts or gears.

V-rods aside, I don't believe Harley has ever made a DOHC engine. Knuckleheads, Panheads, Shovels, Evos and Twinkies have the cam or cams, in the block and use overhead valves operated by pushrods. The exception would be flatheads like the 45 inchers in the Servicar, or wherever else that 45inch motor was used. The flathead has both the cams and valves in the block, just like a lawnmower. No idea about anything made in the early 1900's...

I've heard them called that, but I always called them flatheads...I'm sure people have called them much worse I actually almost bought one: a '38 flathead for $1800. It was in another frame, but had the suicide clutch/shift and was in running condition. Would have been my first Harley. Got a Sporty with a bad generator instead...

DOHC - Double Over Head Cams.

Funny reference but I bet you can tell folks age on whether they reference Double Over Head Cams orDual Over Head Cams ...
Ha! I must be an old guy, then...Double OverHead Cams. I first heard that term in the early '60's, from the automotive world.

"Dual" applies to exhaust systems.

And "Duel" applies to a gunfight...or maybe banjos.
