What kind of a FT/LBS number are you looking for?

You can keep a very street-able 500lbs with a 468

You can also go low compression street-able 496 with 550-600lbs or high compression to get into some crazy numbers.

I was looking for 600ft/lbs because more then that and you get into expensive clutches. I decided to go a smaller route engine wise and make the torque later in the drive-line. It keeps many things cheaper and living longer.

A truck is a system not just a engine.
Torque can be made in many places besides the engine. I am running 4.56 gears because it allows the most torque at highway speeds. A transmission(or multiple) that provides a higher final torque at highway speeds with the right gearing can make a 6 cylinder pull away from a v8.
