There's a good reason for the 4.11's behind a 216, if you ever intend to do anything remotely resembling "real truck" stuff. That engine runs out of torque pretty quickly when pulling a load. The 3.55's that are available from various vendors are for Cowboy Cadillacs that rarely carry anything heavier than an iced down Yeti cooler full of Bud Light.
