Most readily available flathead model?

Greetings, I’m pipedreaming on a new project & wanted to know what would be the most readily available flathead engine, preferably a four cylinder, pre mid 50’s. I suppose it wouldn’t necessarily have to have been used for an automotive application, (stationary, generator, implement, etc) but definitely something commonly found in the Midwest. Thanks & take care.

 

I would guess a model A engine. Millions were made, or is that too pre-mid 50's? Does it have to be a 4 banger? alot of ford v8's obviously and dodge six's.

 

Jeep/Willys 134 Go Devil. Came home in all Jeeps till the 60's.
Gotta be in the Top 5 produced, with How many went to WWII and Korea?

The Jeep 134 was basically the same as the willys cars going back to the '20
and also shares alot of history with the Continnental "Red Seal" engines.

Model T or 28-34 4 cylinder would probably outnumber all other 4 cylinders.

 

You want a car engine.
There are plenty of Hercules, Waukesha, and other industrial engines around, but they make poor automobile engines. They are set up to run all day at a predetermined speed. The cams, ignitions, hell practically everything, is pure industrial. Four cylinder flathead, yeah the Jeeps are probably the newest, the Model "A" is the most numerous and has a lot more hop up stuff available

 

The venerable IHC Green Diamond flat six was Willys design that IHC bought and used from '33-'49.

 

Mopar flat 6s.

1939 - 1960s

 

There were 28 million model T's made. All 4 cylinders.

 

Who built the other 13 million? Ford built 15 million
