nascrap and the 20 car cheating

I’m getting real tired of people who know nothing about performance engines HARPING about this.
Let me explain in a way most people can understand.
The connecting rod was light by 2.7 grams.
2.7 grams is about the weight of one dime
A racing engine rotating assembly is balanced to tolerances of +or- .02 grams it is preferred to have .00grams +or- . plus the balance engine parts are piston,wrist pin,rings and circlips plus .8 grams for oil.
NASCAR picks one connecting rod out of 1 engine per manufacture at random the 20 car just happened to be that car.
TO HAVE A BALANCED ENGINE EVERY ROD MUST WEIGH THE SAME!!
So if one rod was light they all were for a total of 21.7 grams letting the engine reach high revolutions faster that is not counting the pistons, rings and piston wrist pin's
