  • 534 ft-lbs at rear wheels with Magnum 318 in 1992 D150.

    I had my 1992 D150 on a dyno at a car show last summer. This is what it put down four years after I had the engine apart. Third gear with overdrive off.

    Ported and polished heads, double roller timing chain advanced 4 degree, hogged and cleaned out plenum runners. Also gasket matched throttle body to intake, intake to heads, heads to manifolds. Removed casting lines and polished throttle body. Stock cam and manifolds.

    Third line is skewed because I think the tech had the truck in second.
