Are those the aluminum blocks?
The SHP is cheaper than the LSX block... comes with 6-bolt 1/2" head mounting, 4-bolt 7/16" splayed main caps, priority oiling, reuses the stock pan...
Basically it's like getting the topend attachment and bore spacing of the LSX block with the oiling and bottom end attachment of a race-prep SBC. But it uses all LS1 components.
So a lot of the oiling issues with the LS motors goes away and the main cap walk is cleared up by using splayed caps that are substantially beefier. I believe the 1/2" head studs are standard with it as well.
Dart rates the block to 2000HP.
