I worked on New Holland Genesis tractors for three years or so. It's not uncommon for one of the early ones to be pretty hot on the dyno. 300+ horsepower is a bunch out of a 7.5 liter diesel, but I've heard of other 8970s running that much smoke. Be forewarned that the Genesis blocks are parent-bore with no sleeves, so rebuilding requires either a hone job and rings if the cylinders are still within wear specs or a bore job, new pistons and rings. Although I don't think I'd worry to much about the hours being "turned back", as the tachometer/hourmeter is electronic and contained within a controller, I would maybe be worried about a Genesis with 3500 hours that hadn't had any other work done to it. Several years after they came out, we were still getting several Service Bulletins per month on them. One of the most common problems was a leaking front seal, as the steel sleeve on the front of the cranks wasn't hardened properly, and the seal would cut into it and cause a leak within the first 1500 hours or less. Look for a leak there. They also seemed to be pretty hard on A/C compressor clutches. I replaced several of those. If it's a Super-Steer tractor, there are a ton of grease zerks on the front end. Make sure they've all been greased. But, generally speaking, they're a strong and relatively trouble-free tractor, and would be my first choice after a Deere 8000 for a big row-crop of that vintage.
