My truck had the 53' block in it and it cracked. Had to get a new 56' block to put in it. I dont know how often the 53 block will crack but from what i have heard it happens mostly when you starting puttin power to it form modules and programmers. They usually will crack on the passenger side down towards the bottom of the block down below the freeze plugs. Just my opinion on them.

It's a crap shoot. Some make it some don't. Mine is fine. It can be repaired or you can swap the engine out. Use it to negotiate a lower price.

dont really think ill be able to get a lower price. the truck is a 98.5 reg cab, 133,xxx miles, 4" turbo back MBRP exhaust, brand new mickey thompson tires, diablosport powerpuck, and the front end has been leveled. it is a solid truck but the guy is wanting $10,000. the only thing keeping me from buying it is the 53 block and the fact that if it cracks and i eventually have to replace it im going to have several more thousand $$ than its worth .

I have 211xxx on mine and no cracks. The problem is the 53 casting block is mor prone to it than others. Keep in mind this doesn't mean it will crack. If you are going to pour the coals to it as far as power put a girdle on it and it will reduce twist and tendency to crack.

Where did you end up getting a 56 block?

putting a box on the truck wont crack the block, towing heavy through the mountains or sled pulling, etc. is what gets 95% of the ones that are going to crack.

I have 206k miles on my 53 block with a box on it pushing 35psi of boost and no cracks. then again I rarely tow anything heavier than a couple dirt bikes or jet ski's...

Yikes! No offense, but $10,000 for a 98 with 137,000 miles and a "53". You need to come to Texas and shop for a truck.:S:
