Default LY6 question

I am looking for an LY6 for my Silverado build and read that the Chassis cab version came with less HP than the Van and Truck versions. Does anyone know how they got to this hp? Is it just a tune or less CR?

Long blocks change very very little (if at all) for a given engine code.
Meaning its most likely the tune. Some of the stock 6.0s came with VERY low timing.

Okay that's good to hear. The reason is because I've seen a lot of ly6 engines that came from chassis trucks at a lower price and I plan on changing the cam in a house but I wanted to make sure that the compression ratio is still the same.
