The blocks aren't the same. The motor mounts bolt bosses are in different layouts, for one example.

Negative. On the older 12v blocks, that is true. But the 53 block thats used in the 12v is the same as the 24v. My 12v even has the same engine mounts as the 24v.

Interesting, and news to me. My '98 12v has old style mounts.

Tate

Does yours have the extra bosses for the newer mounts, and the second drain hole in the block?

i have a 97 12 valve with the 53 block and it is cracked

Deezil

The guy told me its a solid block, but Ill double check before paying, but it does appear to be fixable if it is.

Question, I ran mobile 1 synthetic in my duramax, can I run it in this thing too?

Deezil

Thanks! Its got full leather interior thats had seat covers on it since new it looks like, same with carpet, has two sets of floor mats on it. Previous owner was really **** it appears so Im sure Ill be happy with it.

No, I originally found out that the 24v mounts were different when I bought one to replace a broken one. That didn't go so well.

If it is a 53 block, use that as leverage to reduce the price. Repairing it is expensive and marginally successful, and replacing the engine with a non-53 block is the best solution. And that isn't cheap. I have a friend who had a 53 block professionally repaired, it leaked, and he wound up spending $4000 on a replacement engine.

Deezil

if it has a 53 Ill probably pass on it, is it easy to spot the numbers?

Tate

Don't be foolish like that. The likelihood of it cracking are ridiculously slim, and if it does crack, you can pick up a 12v cheap as a replacement. You could sell the parts out of the cracked block for what you buy the replacement engine for. There's way too much hype around the 53 block.

Deezil

Oh, ok, sounds good. I just didnt want any troubles.
