Default Whats the Difference?

Whats the difference between a 6.2L LS3 longblock and a 6.2L L9H longblock? Just the longblock, not talking about computer, intake, TB, or injectors.

Any info would be greatly appreciated!

Differences are likely Valve springs, Valves, and active fuel management stuff. The truck engine my have a cam phaser aswell.

I've got a L9H sitting in my garage waiting to be mounted in a '46 Chevy pickup. Brought brand-new off Ebay.

The L9H has VVT, the LS3 does not. Not sure if that answers your question, hope it helps.
