ARC rod copy for GX340/390/predator 420

Rod looks decent enough. Bolt are questionable. Bearings are questionable.

-But Ill worry about those questions later if something blows up.

Looks good. Where did it come from? We have a 420 on a 73 Wheel Horse "mud kart" that might be fun with more RPM.

He posted in Quick Bits about that rod but he didn’t mention the rod, just used a photo (which makes it hard as heck to search for). I recalled I pressed him to share the link. Starts here on post #1,989:

No, just a common metric. My i.d. might be larger than it needs to be. But thats what trial and error is about. Anything will help. Im not looking for absolute quiet just not ear bleeding.

Neat features with the scoop style dipper and the overall lightening milling. Those bearing shells do look questionable and look at little dinged up. Is there anything there that might catch the fingernail? Not sure if I am looking at manufacturing debris, swarf or dirty box (box debris).

The “12 point bolts” are odd. Does that take a special socket or your run-of-the-mill 12 point Crapsman?
