Are 53 blocks most common in 99's?

Bunch of hoopla, we have 2 99's, no idea if they are 53 blocks, don't care. Mine has 173k on it. I have absolutly no fear that its gonna crack.

Thanks guys I ended up buying the truck. Other than needing smaller tires (35's and 3.55's :bang ) and to fix the actuator/blend door issue this truck is great!!

I agree. My 98.5 has 155k and I have never checked to see if it is a 53 and I never will.
