Likely to have a 53 block?
Hi all,
Here to pester you with yet another question. I've pretty much struck a deal with for a '99 2wd five speed dually. The truck has 254,000 miles on it, pulling around 20k pounds. This includes through the mountains-everywhere in the continental US. As I understand it, this is the sort of duty that generally will crack a 53 block if it's gonna crack. I'm not sure if the engine has been replaced in this truck, so my line of thinking is this: Either the engine has been replaced, or IF it's a 53 block, it probably won't crack since it has had the hell worked out of it for over 250,000 miles. Is my thinking correct here?

No, I have not actually seen the truck. That's why I'm trying to deduce whether or not it's likely to have the 53 block, and if so, whether it's likely to cause a problem after all these hard miles.

There is alot of these 53 blocks on the road with only a small amount of them being a problem. It's one more thing to consider in making your choice but I wouldn't base your opinion on just that. Even it becomes a problems there are several options for repairing them now that work, so it's not that big a deal anymore. Every truck out there seems to have there own list of flaws, this is just one for these years of truck. By the way, I have one of them and have never thought twice about it.

I think everyone over states the 53 block. I have one and just turned 325k miles no problems and I haul 18,000 plus 4 days a week. If it has hauled like you say I would not worry. Just like the weak tranny which I replaced at about 250k and that was because I needed a business rite-off. Just my .02

Well, I just ended up getting a different truck-a '98 12v quadcab 2wd dually. It apparently does NOT have the 53 block. Here's why: Yesterday I got the truck up on a lift at a muffler shop and took a good look under there with a light. I looked at both sides of the front of the block, and found a fairly large (about 3/4" tall) number "5". There was no 3 after the 5. There were some smaller numbers I could not make out nearby, I think above the 5. I remember on the driver's side, there was a small square or rectangular area of the block that was indented (i.e. a little "dish" in the side of the block" about 1" by 1". There was no letter or number in that.

v8440, I think youre much better off with the 12V rather than the 24V. Its hard to find anything better than a 98 12V.

Ah, I never heard about the difference in 12v blocks cracking vs 24v blocks. Makes sense though-I guess the vibrations would be somewhat different, at least from the valvetrain.
