Do (or can you) post a photo?

I have a couple Fox Eagles that I have modified (Marvin Miller did the work, he's my neighbor, sort of) and I call them the "Reeves Spl's".  I saw what Charlie Reeves had done to them and decided to do the same. He was running one in his Stuntwagon. They weigh about the same as a ST 60 and preform about the same, as far as I can tell.........

Later, Jerry

I think he is talking about the 60 or 74 developed from the 120 twin, not the eagle 1 motor form the early 70's.  I think they are pretty much the same on the outside, do not know of any way to tell them apart.

The Fox twin was a marriage of 2 Fox Eagle 3 engines. The Eagle 3 had to be one of the ugliest 2 cycle 60's ever made. To see one is to remember it forever. The eagle 4 was more conventional. Both the  3 and 4 were very powerful for the displacement. Doubtful that these are the same weight as a ST60 at 12 oz and the Foxes running around 19/20 oz. The Eagle one was light enough to probably match the ST60's weight.  I think they used a modified Eagle one case for the recent C/L 60 that never caught on with the C/L community.

No, the later Fox 60 stunt was an entirely new case. One piece as opposed to two. At 13.2 ounces it was still no lightweight but lighter than the Eagle, much better looking also.

The Eagle one was a one piece case with those completely useless muffler points on the case. They got rid of the vertical muffler mounts  and put a more modern head on but it otherwise looked pretty much the same as the E1

This is the one I'm talking about with all the extra weight milled off.

You're probably right Dennis. I really don't know except that it is an "Eagle".  

Sure works good. Kind of glad I didn't sell it. I'm looking forward to using it a contest. I want to beat Carter with NO appearance points!

It's a Fox Eagle 4.  .74 displacement and you can get a CL venture and NVA from Fox for it. Lots of power. if ou need it.

I've ended up with one of these in a box of stuff and I'm not sure if it's a .60 or a .74. Short of tearing it down to measure it are there any external details differentiating the two engines?

You do not need to tear it down, the 74 has a 1 inch bore, so you can just remove the head and measure the bore, if it is 1 inch, its a 74 . The 60 is about 10th inch smaller bore I think somewhere around .905

Thanks Randy, I popped the head off and it is a 1" bore. I guess that makes this one a .74.

 Thanks for the info guys!

You could have just counted the port windows and seen that it has four, making it a .74. The .60 just has three.
