I balanced my rotating assembly yesterday, and if my math is correct, I lost almost 4 3/4 lbs. New pistons, pins, rings, retainers = 888 grams, old = 1113 grams (old DC/TRW pistons) New H-beam rods were only 8 grams lighter than stock LY rods, but are bushed and have ARP 2000 7/16" cap screws and should be MUCH stronger. Plus King Pro rod bearings are 4g less than Clevitte 77.
That comes to 237g/ hole X 8 = 1896g, plus the 240g removed from crank shaft = 2136g total weight removed from rotating assembly. (1g = 28.349 oz.) 3126g = 75.34 oz = 4.7 lbs
Anyone know what the engine will "see" because of this?
And then we add approx. 3.5 more points of compression (from 10.0:1 to 13.5:1) and a set of alum Stealth heads, we can do more of this
