Machine shop just informed me my crank was burnt and I have 2 bad rods. They said they have a core that they can try to make work but im not trusting that to much. Where can I find a good crank that won't break the bank?
1966, B Block 383 crankshaft burnt journals.

These guys are pretty much a one stop shop, I bought the car knowing it needed an engine rebuild, not knowing the Crank was bad..damn the bad luck..
Did you pull the engine apart yourself?
I would replace the crank and the two rods. Yea, it can be fixed, but the cost will probably exceed another used crank.

Depending how bad the journals are, the procedure for repairing will either be to turn the crank down or weld the journals and then turn them to match the rest. For any kind of a performance build, you would probably want to invest in another used crank. Ideally you would want to run a crank that has been cleaned up to .010/.010. The rods that are damaged should be replaced with new units.

If 2 rods are bad, your better off buying a whole new set instead of just 2. As my Brother how he knows that! Don't let them talk you into it! They should be able to turn the crank if it's never been turned before. Good Luck
Typically, if the motor has a good bit of miles on it, then the crank probably needs to be "polished" or "turned" to the "10-10" size, which is normal. Reconditioned rods can be had, too. A "recon" rod would be better than a brand new rod, as it would have been "factory balanced" to start with, whereas a brand new rod will NEED to be verified/balanced to match the old rods anyway. By observation, some crank shops can "cut" the journals correctly, but then putting the side fillets into the correct shape/radius seems to be an issue for some of them.
Key thing is to discover WHY that journal had those issues??!! Clogged oil passages? But DO find out why.
Of course, the "high cost" option would be a new "rotating assy" from one of the Mopar parts sources (440 Source or SCAT?). Otherwise, fix what needs to be fixed in the most cost-effective manner.
Just some thoughts,
