2005-2006 Engine Swap

[Randy Grein]

Engine mods? Depends on what you're doing. Street stuff? Probably not.  
Racing? Probably. I had a long talk with Dan Zlock (Zlock Racing)  
about this recently. There's a missing thrust bearing for the crank;  
without it the crank tends to saw into the cases. Weird. 2nd gen rods  
are weak and tend to break racing, a few other things.
