    As miseian has stated, depending on your goal a properly specd truck will do wonders. If running Midwest mainly like me as I am based out of Indy, I don't need gobs of power. The ratio at 3.25 is pretty low for good mileage. More of a hill pulling setup

    I use this
    Engine RPM / Engine Speed Calculator

    For a super single use 39 as the tire diameter

    228k out of mine and still doing well. They had issues with cams on some A26s. They usually fail very early, if it doesn’t fail early, it’s good to go. What is the manufacture date on yours? It may be one of those early A26s they had sitting around.

    If the motor is idling normally, does stink, all gauges check out, via oil pressure, I'd go turbo boot, cac line, etc

    I ran the numbers, on a 18, 3.25 speed at 65, I highly doubt the rpm is over 1800. Lol

    How do
