Im at 40,000 miles in my 440 Darton.
Valvetrain was not set up right first up from vendor. Cam got trashed.
Rebuilt better and going ok so far.
Goal is 200,000 with any luck.
It eats a bit of oil. I dont think the hone job or piston to bore setup was done right. But its tolerable. Next time, Id go 427 to keep parts off the shelf. But no hesitation in doing a stroker again. OEM config..

I wish I could provide some input. I’ve got an LSX 454 crate engine but it’s going to be a while before it’s on the road. It’s going in a Factory Five so I’ve got to build the darn car before fire up.

We have a 454 LSx short-block in stock with a seasoned block & priced very attractively! 
It's a 4.185" bore & 4.125 stroke.
We typically do about a dozen of these engines a year with good results.
