The most important part of a motor are the parts that can't be fixed. Cracks and internal rust are good reasons to give-up on an engine; at least, it didn't overheat.

If you swap to a 2F then you can't do mix-and-match heads/blocks, if you are hoarding old parts for the future. A 2F has one more hole for the exhaust manifold up front, which could be nice for headers. But, finding good manifolds was harder to do than actually finding an engine, for me. You might look under that carburetor and see how your intake manifold looks where it mates/mated to the exhaust.

A split-hood rests its prop on the old valve cover, right?

You can rest it the the valve cover to get more height but there is actually a hole on the top of the bib. With a 2F installed the clip that holds the rod needs to be bent sideways to clear the valve cover.

Was the intake on the 71 still the fat wide one? Know 72 it was skinny. That and oil fill moved to the valve cover.

Got some good news today from the mechanic. Damage was minimal and we shall rebuild. Turns out the bearings have "seats" for a lack of better word, that keep the bearing housings from spinning out. Lots of metal everywhere, but the block, head, cam, crank, pistons, etc., are all in great condition. The F1 shall live again

So what bearing was it?
Pics of carnage required...

I don't see any organization to the parts to get things back in their original spot. I always thought that was vitally important for most all internal parts.

Glad you could save it

Spun bearings aren’t that exciting... seen one you’ve seen them all. In my thread, there’s a pic of bottom of the head where the piston was kissing it on every exhaust stroke. After the crank bearing was spun and pounded it chewed the crank.

Both my F and spare 2F needed more than 3k to repair them. In ‘96 it was $600 for a set of F pistons... now they don’t exist anywhere. In ‘96 it was more than a decent 40 cost... thus they were scrapped. The $300 SBC that replaced it lasted 20 years. I’m hoping the cherry ‘72 350 that replaced it will last even longer... it should. The first 350 had ate a cam before it went in and was always a little loose... but still a heck of a motor.

Did u have a plugged oil passage or something as to why the bearing died?

I am humored by the amount of effort your mechanic took NOT to drop the trans and transfer out. There is NO WAY I would not be dropping those and putting new seals in both as a bare minimum while I had the opportunity.
