Just like some 04 L26's having L36 rods and all 04 engines having plastic LIM gaskets, some 05, all after having metal?
How about the switch in 06 to metal water pump and front timing cover gaskets?
And the S/C gasket change in 06?
Bio: 1200 for an L32 isn't terrible. If you went L36 you'd have to add on the blower, heads, lim and gaskets/bolts to get there. Sure wouldn't be $900, but it'd be at least half that. Save $300 or spend that $300 and get much better rods.
