OT: Pls help me ID my Willys motor

[wdglide]

Its in my Willys. I was told it was an GM Iron Duke 151. However, I am not sure. According to JeepTech The intake and exhaust manifolds should be on opposite sides. This motor has points in it so I assume its mid-70's at the latest.

There are more pix here.

I'm thinkning it might be a Chevy 153. Found some info here. There's a photo of a pretty one. However, there is no info along with this photo.

Early "Dukes" had both manifolds on one side. Later "cross-flow head" Dukes had them on opposite sides. You appear to have an early one. These were put in DJ mail jeeps from early in the 70's, if I recall correctly. More than likely it's where this one came from. You could probably identify exactly what it is (Chevy or Pontiac) by the engine number, but why bother? Goodwrench still offers these motors (cross-flow only), as well as a 3L/183 Cu In. Marine version. I personally like these motors, mainly for their reliability. If you don't mind putting around, they're great. I have plans brewing in my twisted skull for a CJ-3B and this motor still comes to the top of the list for power. I had one in a Baja VW sedan and it was really fast, but that's another story.

Thanks!!

I'm kinda anal. Any idea how/where I can ID it from the block numbers?

Those Jeeps originally had the flat head "L134" 4 cylinder. Just incase you did not know that....here is a good site on CJ3A’s.

Google is where your search begins. I have no links for that info, but I'm sure someone does.

How

Ok, sounds like you got your question answered and there are some Willys heads around here....
How about this one?

More pics here....
My main question - ya'll have any idea if this was an original engine in this Jeep?
It's either a '50 or '51 Willys Jeepster. (VIN badge long gone..)

I believe the Kaiser Supersonic you have could be the original engine. This engine was originally a Continental Red Seal. It displaces 226 cubic inches and produces about 115 HP. Kaiser cast a new "Supersonic" head for it and used it in in Jeeps and passenger cars. In time it became the "Super Hurricane". I'd have to research it a bit to confirm.

The safe answer is that the Jeepster would have been available with the "Super Hurricane", for sure, and if that sort of visual authenticity is desired, it may only require a head change (maybe) to convert the "Supersonic".
