[syrupdawg]

What is the deal with the "53" block that everybody talks about? Why is is weaker and what years models did it come in?

Most often you see them in the years of 98 to 01 . Both 12 and 24 valve.

This link will give you a good idea of what happens and how to repair it should it happen to you.

The casting is thinner. Storm blocks are beefed up more in this area
