Not 100% sure on "pure" reman, last time I talked applications with someone in that group they did sell
1990-ish era la engines but that was two years ago.

Demand differences beween reman and performance crate engines...under the right conditions: low price, economy is not in the toilet, folks aren't scared off by new technology, gas isn't 5 bucks a gallon and so on.....are pretty dramatic.

Let's say I need a 5.9 core to build up. I might find a wrecked 2002 truck in a yard around here, though most yard vehicles are newer. I can see whether it has oil and coolant in it. I can see if it has been hit in the front.

The big volume salvage yards will sell everything they can get their hands on, whether it has been burned in a fire, it has oil or coolant or not, it has been hit really hard in the front, and so on. They don't care, they just want to get paid. Given the nature of their business, I can't blame them. Can't really control what comes in the door at the reman facility.
