I am prepping my parts for bob weight calculation to balance my forged crank.
Is 1 gram max difference between pistons acceptable for a 440 that probably won't see more than 6k rpm or so, or do I need to zero them out?
Out of balance of 1 gram then add the dynamics of 2,000 rpm, that actual force squares at 4,000 rpm, then that force squares at 6,000 rpm.
Your seat of the pants wont notice it, but in the motorsport theory of everything counts...maybe its worth it.
I had a 71 340 engine with 150,000 mile on it and one rod was 42grams lighter than the heavy one, must have been down on power fighting off physics like that.
