DOHC is correct. There is really zero way for anyone here to accurately provide you with a cost estimate for rebuild without putting in a bit of inspection/inventory time with the motor in person.

This much I can tell you. At one point, the cb350 was nearly the most mass produced motorcycle in the world. The sold around (iirc) 300k in North America alone. Parts are not difficult to come by. Whether it's NOS, aftermarket ot used, the market is awash with cb350 parts.

^That said, it's a great motor to just buy a running lump, change some seals and gaskets, then go. Also, a lot of machine shops charge per hole, so a valve job and hone will be priced per. I can see just that costing you in the $300 range. Total rebuild would be under $1000, but you can buy a minty lump for a couple hundred.

I am open to the idea of a new engine sounds like a great idea in theory but how do i know it is a strong runner? I mean my current engine runs and I just removed pieces of the camchain tensioner from the oil pump filter.

Unscrew the oil drain and stick your finger in there to see if there's a bunch of metal. Pop off the top cover and look at the cam and tensioner. An honest seller should't make a stink. You can also pull off the generator cover, tip the motor so oil runs out and see if a bunch of junk is in there. While your at it, see if it has compression. An eBay purchase is a tough one, so you'll have to rely on the ad description and pics, then hope the guarantee policy covers your ass.

any old 350 that has not been rebuilt is going to have the exact same issue of the rubber bits in the cam chain system being rotten.you would need to buy a verifiable new parts build to be secure

Hm. or that.

if you study the factory service manual ,indeed all of the service limit checks that should,no must be performed are quite daunting for a novice mechanic.heck just getting the pistons and rings in the block is a pain in the ass. but the procedures are clearly described and someone with some backround and the knowhow to use a dial indicator is far ahead of the typical drone
that said one of the often overlooked areas is the small end of the rods.. a week spot for any vintage honda that has been run hard and long on old oil with a little rusting thrown in
