Thanks for sharing.
What I wanted to establish was whether I could machine my 2.5 carrier for clearance for the 2.7 crank. Unfortunately my carrier is damaged. So it won't be reused.

Thanks for responding.

Yes, I have found that people won't share info about this particular engine. For other cars I work on people share willingly and freely what they have :confused:

Some people claim these cranks can't be ground because the hardened layer is too thin. Did the machinist test the hardness of the reground rod pin?

I just measured my own crank and found 0.0012"...

Great.
Thank you.
So, what I'm trying to figure out is if a 2.7 crank installed in a 2.5 carrier would cause the rod bolts or big ends to contact something. Most likely the areas where the arrows...

Physical difference in crank carriers from 2.5 to 2.7?

As you probably have guessed I have never compared them, but from looking online I can see that the main bearings are mirrored, i.e. the tang is on opposite sides.

I actually didn't know that the 2.7 is more reliable. I thought the 2.5 was the most reliable engine of them all due to having the dual row bearing and thicker cylinder walls.

Thanks. Good to know should I decide to buy a new engine.

Unfortunately they don't help when the owner is an idiot and forgets to fasten the coolant cap.

Thanks for your input. I'm take all advice to heart.

To me the engine is the weak point. The rest is quite affordable.
