A series of photos will help you put things back where they belong in the future ( depending on how long that might be )
I would not run the engine any more until you have it out and look into the internal knocking problem to not be causing additional possible internal damage to it
If doing a lot of work yourself a good machine shops advice and worked performed by them will be a very big help to get it all correct and back together in good condition ( to stock specs or as close as is possible )
A lot of info on this site is in the home page header

All posts go into a library for future reference for many years on this site
Recommend asking one question at a time so all info is based on the subject asked
As you know the engine needs some low end repair issues so I think I would just pull the engine and repair what that needs for now
The trans may be just fine and work for a good while after the engine is fixed and replaced but you will not know the condition of the trans until you can drive the car
Will be more labor intensive to do it that way but could save you the expensive cost of rebuilding a trans that does not need it and apply you skills to the next issue needed to get the car road worthy ( Brakes maybe ?)
How many miles on the car now ?
Jason Edge who is the web master here and one of the very best authorities on the subject of our two year of Antique Cadillacs did a complete rebuild on his 64 429 that will be a wealth of info from soup to nuts regarding tips procedures and rebuild parts new or used for our Cadillacs
Jason and Russ are our two major part suppliers on this site for our cars
Most parts and good advice you will need are available right here on this site
Welcome to the world of restoring a 63-64 Classic Antique Cadillac !
You are in good company with those who live and breath our year Cadillacs ( The best year Cadillac ever made in my own opinion )
If there was no significant scratching or abrasion on the rod journals due to the rod bearing failure, you got lucky. If there is deep scratching, etc they will need to be reground and new undersized rod bearings used. If only minor scratching can just be polished.
if your crank isn't destroyed after that, buy lottery tickets, because you're the luckiest man on the planet.
I would not just slap new bearings in, you need to have the rods checked now, if there was enough room to have a bearing spin, then it's at least a 90% probability that that rod's bore is oblong from the hammering it took. You won't necessarily need to replace the rod, but you need to take it to a machinist who can check the runout, grind the faces then hone the bores out. It isn't a very long operation, but you need to do it when you see this.
Enjoying my education on the subject
That bearing is toast !
I have never seen a spun bearing on one of our engines on this site since 2006 and on the site daily since then
So surprised by this
I don’t think a lottery ticket will be in my future. It doesn’t look good. Does anybody know where to get a good crankshaft? This might be beyond machining.
