I Have Two Questions Can You Take A Crank Out Of One 360 And Put It In Another Block With No Machine Work?

It is possible to do so but I would really look twice before bolting that baby up! Machine work is cheap as doing it twice really sucks.


If You Spin A Main Bearing Is It True That You May Have Damaged The Block Beyond Repair?
Thanks


Again, a machinest or a good look will tell you if you have damaged it. But more than likely, no. You'll have to look everywhere in the engine to be sure that something else didn't take a crap. The bearing itself can be replaced. No problem. I'd wonder about metal shavings in the oil passages and other damages through out the engine.

If it were a cam bearing, the cam is probably damaged.
If it is a crank bearing, the crank is probably damaged.
I'd go through the whole engine and run a bottle brush through it before I proceed. (Actually, my machinest would be doing the work. I'm getting lazy and rather pay.)
