318 build check from you experts

Rumble, I think you have a hard time reading between the lines.
OP asked for thoughts
OP mentioned the alloy heads.
OP mentioned new pistons.
The rods, as you know are the same between the LAs and sorta worthless in a rebuild.
OP wants a new cam
OP has an AG and several carbs.
The truck is pushing 3800 pounds and the tires will be 28s
So Come on,
The only part he might reuse
"mostly because he has it", his words,
is the worthless 318 block.
But worst of all Spokane is at 1843 ft elevation.
Why would you sacrifice something like 150 to 200 horsepower just to keep the stinking 318 block?
