Default Stock Crank Weight?
I read somewhere that the stock LS 3.622 crank weighs 143 lbs? If that true an aftermarket crank weighing appox. 50lbs is a no brainer upgrade??

Where did you come up with 143 LBS? I just put a stock crank on my bathroom scale, it weighs 51 LBS.... I never heard of anyone changing the crank to save weight.

You really couldn't lighten the crank any or it would be out of balance, weakened, or both.

I could be wrong and stand corrected if you are right.

Stock is anywhere from 53-54.

The strokers are ~ 48-55 depending on manufacturer.
Callies typical LS1 stock stroke cranks are 44-45, and you can get them as light as 34.

142 lbs.?, Good Grief! The crank in my 622 doesn't even weigh 100 lbs.

Try 55ish for a LS1 crank or call an engine builder for the precise number.
