[Shotimes] Rod Bearing Change @190K miles

[Ron Porter]

As hard as it is to believe, there are SHO drivers with featherfeet who can
lug an ATX.

There has been speculation that the ATX does not allow the engine to "lug",
and therefore reduces wear on the bearings.  With an MTX you can run the
engine under load at real low rpm's which is what is theoretically bad for
the bearings.
