The 340 Forged Piston Is So Heavy....

Typically weight is removed from the underside of the slug next to the piston pin...

I'm repairing the SB 383 that I bought for my dirt late model. I was really concerned about rotating weight until I weighed my 3.79 crank... 67 lbs! I guess saving a few hundred grams on light pistons and rods won't mean too much!
