Hey Gnarly,
Have you looked at the Crower cams? Crower makes high quality stuff. Some interesting grinds here. Notice the wide LSA for EFI vs. narrow but requiring high compression for carb:

Thing is, there's no reason you couldn't run the wider LSA in a carb'd engine. Spreading out the lobe centers increases vacuum and idle quality and decreases overlap. It tends to flatten the torque curve. Honestly, I'd rather have a fairly flat torque curve with more torque down low than go for peak torque and give up torque down low.
"Area under the curve" is where it's at for a truck you drive a lot.
