All the LSX based motors have 6 bolt mains, 4 in the normal configuration and 2 side skirt bolts. Iron and Al blocks, 4.8, 5.3, 5.7, and 6.0

Not really splayed mains like a normal SBC. The 4 in the normal configuration are straight "up and down" The one on each side goes in perpendicular to those.

Ok, I figured they called them splayed caps.
