All of this is great information. I have no intention of building a full on race engine for this Truck. The cam choice will be a solid lifter design, good torque and mid range power.

As for the block, I will look at custom pistons with a bore of .060 - .080 . The block will be decked enough to make it straight and flat. Just a good basic rebuild with balancing of the rotating assembly.

The will be one of the "848"'s I have. I may mill it slightly, no more the .020 - .030 at max. The valves will be larger with some clean up in the runners and bowls, nothing extreme.

I don't want go away from the stock intake and exhaust manifolds. I may use a larger exhaust pipe and muffler to aid in breathing.

Overall I want a solid, period correct 261 with a little more grunt and good drivability.
