I'd look into what Scoggins Dickey is using to build their L8T. They are advertising their setups in my NMCA Magazine

Does anyone know what kind of coatings are on the stock GEN V stuff?

??

looks like stock block
callies rod
wiseco piston

i say low compression because every other direct injected gas engine i know of is at least 12:1.

Yeah, I wish GM would have been more competitive with them and did 12:1 at least and 11.5:1 in the 5.3. They also may have been more limited with a 2 valve pentroof chamber since everyone else uses 4 valves with a centered spark plug. I mean even the modern HEMI has a central plug, but of course they haven't updated it to DI, and supposedly, according to click-bait articles, Stellantis has having the HEMI killed.

I mean the LT6 has 12.5:1 compression apparently. But maybe the L76 put a stop to 12:1+ since maybe they wanted the L86 to be a "premium recommended engine" and didn't want to create differences in the L86 and LT1.
