this is a post from the past I added some good info on it if you read the post
and yes there are tons of 53 block info if you search or just google it also

 

What year did the 53 block come into production. I have read thes articles but might have missed it? Is tit when the ISB engine started?

 

1998 was the first year and there are 12V #53's and 24V #53's

 

Thanks Just wondering.

 

Thought there were some late 97's also?

 

maybe..

 

Just finished crawling around the nether region of the 2500.

NO 53 on right side...

On the left side I saw a DIAL indicator marking date?

A series of 1/4 inch tall numbers and directly beneath those a single "5" digit.

Could this be correct?

Does this mean I avoided the ISB 53 block?

Truck was manufactured 11/97 in St. Louis..

THANKS

 

Yep, though I have never heard of a problem with a 12V 53.

On second thought, I think there was one here, but not like the 24V guys.

 

If you have a series of small numbers, you may have a Mexican block.

 

That is what I saw. And one digit under that group about 1 inch tall--

just a single "5"

I had read the 24V had problems then someone said that a few 1998 12V might be included and I was nervous.
