Anyone care to explain what is a 53 block
The # 53 block casting has inherently thin water jacket walls that are susceptible to cracking. Frequent and/or heavy towing, failing to let an engine properly warm after a cold start, and engine overheating can contribute to the development and propagation of cracks in the water jackets of these engine blocks.

And on another note those dash pads on the first gen. rams were horrible for cracking , but they weren't to bad to replace.
