Thanks Mike
Actually just got the plate and nut built yesterday. Hit it with the impact both directions. It didnt budge, but over time I think she will break loose. I think I will also pull the dist and pump some oil through the engine. Im not in a hurry, I only bought this one to keep it from going to the scrap yard.

she came loose today! I could hear slight noises coming from the exaust when i hit it with the impact, so I got the 1 inch drive rachet and rocked it back and forth a bit and now she's free.

That's whut I'm talkin' bout!!!! Good job 319. And to tell you the truth, it didnt' take as long as I thought it would. You musta been real diligent with that impact wrench workin' away at that thing. So.....what's next for that bigol motor??

Thanks guys. I was surprised that it gave up so easily. Its been soaking for a while in the diesel and trans fluid, but only got the impact on it last week. I used a 1/2 drive impact instead of a 1 inch thinking that the vibration would help get some fluid behind the rings.
All of the cyls had threaded plastic caps in the spark plug holes and they were pretty much paint sealed except for one. it showed evidence of a rats nest. I think some urine made its way into the cyl.
I dont really have a plan for it, but I do want to hear it run. I took the valve covers off and it looks like it was never run after the overhaul. (The spec sheet shows new .060 pistons.) So for now, check for damage, and drain the oil/diesel/trans fluid in the crankcase. And??

Folks like me and 'Yote.....we look forward to hearin' 'most anything run....

I'm pretty glad about you gettin' the upper hand on that thing.
I'm also curious about what all came with your "crate motor"...?
Was there anything more than what we see in the pic's...? It would be nice to see a few more pics.
I see the mechanical tach drive.....and the super HD mounts and the air compressor.....and that alternator....(I'd like to see more on that, too)...

That thing is sure somethin' to be proud of.

Tonight is the first time I connected this thread with the PMs we had exchanged.

First, if I find an irrigation stand to sit it in, would you want me to grab it? You could run it in the stand by running a garden hose in the surge tank and letting the cold water circulate and run over. Messy, but works.
I'll also be on the look-out for any junkers here, in case you need more misc. parts. Some of them even had hand clutchs on them.

Curious? Bored .060, does that add enough ci to bring it up near or over 500ci total?
If it did, and someone asked if it was 478, 351, or ?, you could honestly say, "Naa, it's a 503.5", or whatever. Makes good braggin' rights, and size they had never heard of.

That's another thing that's fun with these motors. People are curious enough about them, that a guy can kid around with them some, before explaining what kind of critter they're looking at.

It will be interesting to see what kind of project it will lead you. Maybe a go-cart, dune-buggy,---who knows?

Whatever? Best of luck!!!!

Oh, as the grand-kids would say. That little "happy dance" you gave when it rolled over was in order for an old guy.

Rockdriller, the compressor had an overhaul tag on it as well. I dont know anything about the application though. It looks like it uses pressurized oil from the engine, but thats a guess. It came with a new carb, aircleaner and 2 massive looking motor mounts, and a new fan blade. I will take more pics when I get back out there.
Cayoterun, thanks for all your help and the trip down memory lane. I will stop by the next time I get up there. We had several irrigation stands at the farm, set up for 413 Chryslers, but I think my brother sold most of them. So yea If you find one grab it and I will send you a check.
I am going to need a flywheel before I can try and start it as well.
Thanks to all for your support, love this site.
