[QUOTE="flyerdan, post: 104324, member: 2510"] The 700 series came with three engine options, the 700 and 720 have the Wisconsin air cooled V4, the 721 the Deutz, of course, and the 722 has a Ford liquid cooled. You might find an engine from one of these, the benefit would be that the fittment problems would be solved if you could also get the mounts and u-joint fittings. What you might also consider is figuring out what ring diameter would be needed if your cylinders were punched out to round again, find the closest size regardless of make and match the cylinders to them. Then have a couple of pistons made for them. That should cost far less than the $2100 or so that you're looking at; downside is that it would be a one-off, but should give you several thousand hours of running before it's an issue again. I'll take a look at the Deutz section and see if it gives any cylinder measurements. And it does, this gives all the info needed for some frankenpistons.
