Advice on buying junkyard engines?

I've got a guy at a dodge truck recycles I have worked with for a long time so I trust him. I got my 360 LA from him he said the engine and trans ran good when the truck came in it did have 95,000 on them. $1500.00 for the pair been happy with them ever since runs good for a low compression motor doesn't smoke trans shifts good. That's the second engine I have bought from him
