It's not just from a heavy clutch, 1/3 of the CW cases have been automatics. And the engine mount theory, no dice. I came up with that 4-5 years ago, no response from anyone in the know.

Just make sure you have someone build the engine that knows what they're doing, use the correct size main bearings(there are three different sizes if I remember right) and if you are using ARP's on the mains, make damn sure you had the mains line bored and are using the dowel pins.

Any engine can walk, the 7-bolts just seem to have the problem more often than most motors.
