I got my car home from Florida. Drove it from Lakeland Florida to del rio Tennessee. Roughly 700 miles. Car did great. Only threw one belt. So now I got the block and crank that cam with the car in th garage and I have a few questions
Another 340.

The blue marks most likely indicate the crank is .010 on the rods and mains.
The rods look different because they have been balanced. That is perfectly normal for OE rods to look like that after balancing.

So do they need to be in an certain order. My plan was to just set the crank and rods in the block loosely and cover it with grease till next summer when I get the rest of it together
Somebody was in the process of balancing all the rods to the same weight. Need to go through the rod balancing process to get all 8 right.
Correctly done, you balance each end of the rods.

looks like rods have been reconditioned and balanced. Crank has been turned and maybe balanced to. Have a shop check it out before assembly.
That makes since.
Spray some 10w30 motor oil on everything and bag it.
Looks like an incomplete balance job.
IMO, a new set of Scat or Eagle does will be cheaper, Unless your doing the work yourself.
Block looks great.

Block looks great.
Get some fogging oil or LPS spray for long term storage. I have mixed STP and moly grease before as a rust preventative but good luck getting it off! Nice 340 -1 block there...
I went with the 10w40 and assembly lube. I don’t have a lot of room for storage so I put it together loosely and bagged the whole thing. I thought about the scar rods cause those that came with the car look a little rough to me but I’m no expert.

That appears to be a cast crank
What are your future plans for horsepower output?
That is a steel crank ALL day, check the wide parting line, and the drilled front and probably rear rod journal, it looks to be an early factory 340 crank.

All cranks are steel - cast steel or forged steel
Hard to tell with out having it in hand. I'm from MO

If only one of the rods has not been ground it's likely it's the lightest of the 8. You balance the rods to match the lightest one.

Those rods will be fine...just a little rough looking. How often will you be looking at the anyway?
