We know it's not aftercooled (meaning an intake air cooler between the turbo and intake manifold, right?) because we can see a straight shot pipe from turbo to intake in one of the pics. As best we can tell the repower was done circa 1982 or so. So assuming it's a 6BT, is that a decent mill? What's it's likely redline? What are the odds it's being overreved by the 5.36 rear end? After having written the above, I did some googling. Found this site in reference to the marine version: http://www.tadiesels.com/cu-6bt5-9-m.html From there there's a power/torque/fuel use set of curves: http://www.tadiesels.com/releases/Cummin...rmance.pdf It's dead clear that if I can keep it down near 1900 - 2000rpm at least on the flats it'll be WAY happier.
