Aftermarket Cranks

Larry, I thought your post was right on before it disappeared.

I just read the whole stock section in the new 2013 rulebook about a dozen times, didn't want to miss anything. Found the following,

"Any special equipment export kit
(superchargers, dealer-installed options, etc.) automatically
disqualifies car."

That should take care of the group 19 AMC stuff.

"Lightening of crankshaft other than normal balance job prohibited."

How can turning a 2.437 journal down to 2.200 not be considered lightening the crank?
That's almost 2 lbs.
