Just looking at this engine explains why they call diesels “oil-burners.” It takes a long time to go 170,000 miles with only 135 hp. Todd longs to add a turbocharger for those uphill runs so pedestrians will stop passing him. A factory four-core radiator, dual batteries, and Hydro-Boost power brakes come as standard equipment here. The original TH700R4 (above, left) was rebuilt with extra friction material in the clutch packs and a high-performance Second gear servo to prevent transmission slip. An auxiliary cooler was added to keep it cool. The NP208 transfer case works just fine with the stock slip yoke and is protected by a high-clearance skidplate that follows the contour of the aluminum case.
