Pictured is the block numbers I just installed in my truck.  I removed the infamous 53 block. After attempting to start with no luck.... I researched and found that the back of the cam gear with the newer block has a tone wheel where the original only had a notch.  I'm in the process of swapping the cams out because I'm sure this is the reason for the no start.  I would like to identify this block for future reference if anyone can help me out.  1998.5 ram 3500

Need more pics of the block to tell. I did a swap in 2017 from a 53 block. I bought it from Cummins it was a remanufactured engine long block.

Thats a Mexican Block. Had one i  my 98 24v and I assume it was a replacement for a cracked 53 before I got ahold of the truck.

Maybe a Storm because it's got the holes for p-pump. I assume it's got a hole for the 12v lift pump
