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
