Ok I got a quick question, am I seeing right I was looking for the number on my block (2000 dodge ram 2500) and the only one I could find was a 48 is this right also I looked at my second truck (2001 dodge ram 2500) and it had a 55 on it same spot driver side by a big wire harness . Are this good or bad thanks!

I have a cracked block. I think that it is a 53 but after the crack, I don't care to look. 53 or not it is still cracked.I plated over it with gasket (copper) silicone and then bolted it to the block. So far so good.Can't seem to find a fix that is economical or reliable.
