I went looking for one of these then quit after doing a tuneup on an ‘04 Dakota with the PowerTech 3.7 V6. I can’t say it’s not a durable engine. This one had 300k miles, which is 100k more than anyone could expect without an overhaul. It gets about the same mileage as the 4.7L V8 it’s based on. Still, I’d avoid these…
