Need help with block ID

I found an engine block that is supposed to be a 360 that has been fully machined and ready for assembly. The price is right and I need to know foor sure what it is. There is a casting number on the block above the starter 3614230-2. There are no other raised castings that I could see. The block is wrapped in plastic and coated with grease in the corner of the guys shop. Is this enough info to ID what this block is? I want a 360 to put in my sons 79 stepside 4wd to replace the 318 it has now.

Thats an early 400.. Could be the cold weather block, not what your looking for but probably worth picking up...

3614230 is a 400 big block...

It's just a block with main caps. No other internal or external parts but I can have it for $100

Bring it home... Just the thing for a future stroker project...

Look at the main webs.. They are all good but the best ones have thicker main webs... I borrowed these pictures from 440 Source..

Normal web



Thick web..

Thanks, I'll check on it.
