Interesting.

ZZP lists the same SKU with at least three different descriptions on different pages. Compare this one to the one RJ linked to above. It says, “This LNF engine uses a Gen 3 "sand cast" block, larger oil pan, higher compression pistons, and several enhancements over the Gen 2 LNF. In its stock form it makes ~10 more HP than the original LNF and can handle up to 400WHP.”

Leaves me wondering if the sand cast block is better and if so, why.

Sand cast has less possibility of porosity as opposed to die cast

 

The 3 are all the same, different marketing.

 

Yes, thank you, I understood that, and appreciate the broad selection ZZP offers and the effort they put into explaining how their products fulfil various needs.

They offer a “Gen 3 LNF Short Block” (huh? Gen 3???) But they explain very nicely:https://zzperformance.com/collection...nf-short-block
