Well I found two $2000 Truck Coyotes. One 10 miles away with 100,000 miles on it and the other 100 miles away with 10,000 miles. Reading an article that says the Boss Manifold really works on these guys. Intake cam is high torque so no torque is lost on low end and the Boss manifold will do about the same as any Gen II engine at top end. Just change over the cover, oil pump and add headers and install. It seems the 10,000 mile engine is the best deal. Some yards are trying to sell 250,000 engines for that same $2000 price plus or minus $200. Although most are in the 50,000 mile range.
