Chrysler LA / NASCAR 355 cu. in. crank shaft

The '72-'73 340 piston had a 1.740" compression height. With the 3.454" crank that started this thread, that's .010" down on a 'factory' 9.6" block height, or the same amount above on the common 9.58" blueprint height.

The Sealed Power forged piston part number was L2385F, but it's been dodo for years. I'm not aware of anyone making a '72-'73 replacement piston at the moment.
