Any good places to demandate a CM870 in South Dakota

Bulldog77 I wouldn't be afraid to have it done at that mileage. I don't know when you plan on doing the in frame but if you're planning on letting it go for another 300000 or so, having the D mandate done now will be keeping the soot out of the engine and allow you to take a little less risk in pushing into those miles. There would be really no downside to it. But I can't recommend strongly enough that if you're going into those miles you definitely want to have your main bearings replaced. That's what the ultimately got mine at 1.15 million there was nothing wrong with the cylinder and pistons and the head had some heat cracks from a piss poor D mandate I had in it causing a lot of excessive heat and pressure but was holding its own fairly well.
