843 g. vs. 701 g.

i weighed a stock hemi piston - 843 grams.

new pistons going into the 540 - 701 grams.

that should take a load off of the reciprocating weight!

Sure will help! that is 2.5 lbs for pistons alone. Then add the weight taken out of the crank and that is a lot less metal swinging around.
