440 Source Balance Job

Mopowers, I’m not a machinist, but I do run a 440 Source 512 in a OE 440 block.
I had the balance checked before assembly. It was 4 grams out.
I say, have it checked just so you have that piece of mind in knowing for sure.
Tons of torque.

Four grams... So, a seventh of an ounce..... How much does that oil spinning in the crank weight?

Add to that was it the balance done by 440 Source that was 4 grams off? Or was it the local shop that was 4 grams off....
