I think the shoe is the better idea of the two. stick a nice thick piece of Delrin under the chain with some sort of adjuster on it, is about all you need

Had a 4 inch dia piece of ultra high density polyethylene for the shoe.  3/8 bolt comes in from behind to adjust the tension.

Will that take the wear of a chain rubbing on it? I would think that something that spins up against it would last longer.

Thats all they use in the chain case of a snow mobile Vinny. They usually run a double chain but there they run a lot faster than this application. I tried sawing it in the horizontal saw, it took about 5 minutes to cut in 1/4 inch, but the chop saw in the cabinet shop made short order of it. Its on the slack side of the chain so no real load and a bit of oil too.

We use to use them a lot, once the grooves are 'cut' it will run on the chain rollers.

Built the cradle mount for the gearbox, crossmember and engine bed.

Normally for me it is all the little things that take so much time on a project like this Greg. You just need to keep chipping away at them and you will have a runner. Looks good.

Thanks,
The little things certainly add up. As a general rule I figure 20 minutes a part, 3 parts to it, it will take an hour, some more some less but an amazingly accurate average.

Got the engine fired up, it had a horrid injector knock on the front cylinder. Tried swapping injectors but the knock stayed in number one. When I'd break the line it had almost no effect on the power and it seamed to be pumping way too much fuel. There's a check valve at the top of the piston in the high  pressure pump, thought it might be stuck so I gave it the atf acetone treatment overnight with a tube feeding it. The next day the knock was gone and breaking the line now makes the engine die.
Was given what turned out to be the rear driveshaft from an 80's Bronco. Looked like a likely candidate, so it was shortened and adaptors made to mount to the gear box and flywheel. Also made up a shield for the flywheel.

Digging the build, like watching how this is coming together, is that the same motor? Cleaned up nicely if it is.

I have added a picture, of a chain adjuster I had on my bike. Thought of it when viewing the picture of the chain drive unit. It has a spring under the shoe and auto tensioned the primary drive chain.  The way you did the tensioner is just fine, the bike had the same design and worked for 10years plus.  Just sharing another design of the same part.
