He's in Australia.
I know that. That wasn't my question. I was curious if you'd every heard of some place checking the casting numbers?

i have never lived in a nazi smog county.always just apon bringing it into the state or selling/buying. When doing engine swaps smog referees can and do check things like engine numbers to see if it is what you claim though.283 or a 400?part of why the stroker 6 is nice.

The later nvh stamped blocks are a better choice for any build.
I know nvh means noise vibration harshness and my ‘92 block stroker definitely makes a little more mechanical racket than the stock motor in my 97. But what other differences are there? Is the newer block stronger, more reliable etc?
Here is a link to get started. The second is a stroker forums. Russ Pottenger is the guy to talk to from my research.

I did some more reading and it sounds as if the main bearing girdle was one of the big changes and that can be added to older blocks but also needs to be shimmed to run the nearly .5” longer stroke 4.2 crankshaft which, in turn requires oil pan mods. Any of that sound correct? I think I saw @SkylinesSuck modified the oil pan for girdle clearance?

Yep,we both used a hammer on the front of the pan for the little bit of clearance. It isn't a big deal. Keep in mind that changing main bolt torque and fastener type can change bearing clearance and bore shape. Thats the kind of thing you do on a bare block so you can measure it
At present, this is purely curiosity on my part. But thanks. I enjoy the discussion.
And I built them before he did...just saying

We have no idea what its like over there. He'll have to tell us.hopefully the links we provided can get him a block his accessories and motor mounts will work with.

Good links. Appreciate that. Your profile says 3.0 under engine; Toyota, BMW, Hurricane…typo?
Dude, that’s just wrong….
I've tracked down a couple of motor options locally. One is from a running 98 and the other is from a wrecked 02 (both TJs). I've read through @Chris guide to block interchangeability and noted the warnings about engine mount locations being different between the XJs and ZJs over that transition period.
Its not clear to me if the 2002 TJ 4.0 block going into a 99 TJ would have these same issues? Does anyone know for sure? I'd also like to be able to move all my 99 accessories across including the new A/C system I just got working but its the engine mount locations I'm really focused on if anyone knows...
