Engine identification ?

[51 CJ3]

Okay, it took a little digging but, if I am tracking all of the sources that led me to my destination correctly, the supersonic should be worth about 8 extra hp according to Wikipedia. They have the Henry J engine listed at 68 as compared to the Go Devil at 60 hp. Both are L134. Both came from Willys. Unfortunately, Wikipedia isn’t always the most reliable source of information but they usually have references to back what is posted.

Check that they rate HP at the same RPM and at what torque...

In a Henry J, the rear axle ratios would have been a lot different that in the CJ's so that gave a bit of room on specsmanship. After all - 1n 1950 or so, you would expect your family car to have a lot more horsepower that that old Jeep you drove through Belgium!
