Title: Gpw vs cj3a
Post by: Dajeepman on January 31, 2018, 06:47:09 AM

What's the difference between the Gpw and cj3a motor? My friend has a gp3 motor he will sell me for 350 with standard bore. It was in his 52 cj3a. I think it was swapped into it at some point.

The GPW engines and original 3A engines are both basically L-134s.  There are some minor differences, but you really have a "bolt and go" situation.  The major difference is the front engine plate, but if this GPW engine came out of a 3A, then this issue has already been addressed. 

I have a GPW engine in my 3A.

And by the way, that is a great price for a running GPW.  A guy looking for a GPW engine for his GPW Jeep would probably pay 4 times that amount for it.

Hawk,
I just have to say, everytime I look into your engine bay I'm just amazed at the quality of that restoration.
