Stationary F-head compression ratio

[dago_red]

Awhile back, I acquired a cylinder head for an f-head 134. I'm all but certain it is off a stationary engine, maybe for a generator or welder. The pan had no skid plate on it and the owner (who I bought my M100 from) said it was from a stationary set-up

Unlike the head on the f-head in my A1, which has the compression ratio (6.9) stamped onto a boss, this stationary engine has no stamping to indicate CR.

So, I was wondering, would anybody know if the CR on the stationary engine is the same or perhaps different than a regular F-head? I know Willys did have some variations in CR- both higher and lower than 6.9

I don't know the year of manufacture for the engine, but it was all OD paint on the thing.

The answer is only the 6.9 head was used.

You can find this answer in the Kaiser Jeep Industrial Engine Service and Parts Manual IS-1009 dated 1969.









The only F-134 cylinder head listed in the IPL section is the 6.9 CR PN 937454

Thanks Wes- looking at the last page, seems like it was the same engine specs. If it still shows 72 HP then probably all is the same.
