why would you say that the 8.1 is no LS motor of any sort?

Everything about it is the same, from the oil pan, to the main caps, to the symmetrical cylinder heads, fireing order, and fuel injection system. Nothing from a 454 or 502 is the same as the 8.1. Not the oil pan, not the block, not the heads, not even the intake.

Everything is like an LSx except the canted valves. That is the only part like the traditional big block.
