If you're running 4.56's, then don't hesitate to run the xe 274....but anything less and a 318, you'd be fine to stick with the 268, especially if you're running eddy heads.

What stall? If it flashes high enough I'd go a step higher cam with a engine like yours, perhaps a XE284H.
When it takes more than a sweet mullet to prove you rule at the trailer park..

Look at whatever cam catalog you have decided to use. Go clear to the bottom of the list where the biggest and baddest cams live. Look at them, don't buy them. work your way up the list. Its OK to close your eyes and imagine what they would sound like but don't buy them. When you get to the one that looks too small but says it will work in a 318 truck, BUY IT.
In theory, there is no difference between theory and practice. In practice, there is.

Small motor in a pickup which by nature is heavy? Go for the smaller cam. Your heads will take care of any breathing issues there are and don't need to be crutched by a big cam.

Normally I agree with you, but if hes making 300hp @ 5250 he's also making 300lbs-ft @ 5250. Remember that \6's ran these things too with realitive ease..
/6 engines made these trucks move, sure, but a ten speed bicycle is faster off of the line. With the gears, stall, and tires this guy is running my guess is he wants to go fast.
Eddie heads, big valves, small bores, an XE-274, and valve shrouding are, at least to me, a recipe for a really lazy motor. Even if it produces decent numbers up top the usable power curve down low is going to be flat.
All of this aside, you if plan on going big block later on in the life of this project, why blow $1400 on a set of heads you can't reuse on the new motor?
