Guess that noise

Dropped off the engine a while back and without even taking it apart we concluded that the crankshaft is the problem. Whether it was cracked or just balanced incorrectly it has to go. I've had it apart roughly 3-8 times with hamsauced bearings and it's a sour subject that I'd just like to put behind me.

I had put together a barn find 360 engine for fun to drive the car until the snow flies but I hurt it as well (blew a head gasket and lost compression on #5)

Option 1
Use crank from barn find 360 and use my old stock rods/405cp pistons. Dingle ball hone with new rings.

Option 2
Buy scat internally balanced crank. Send scat I beam rods/H116 pistons off to get internally balanced. New Balancer needed.

Option 3
Buy Internally balanced 408/416 (have a standard bore 340 block) scat rotating assembly.
