Worth it to balance rotating assembly?

Can of worms time here lol.

Never seen a factory balance anywhere near RIGHT!
I've done hundreds lol...
The only one I would say was even close was a 69 340 engine...

This is something I did for a living, good fun indeed.

Balancing the crank is in fact the easy part of a full balance!

Pistons are the hardest part to balance as they don't have many areas for lightening.

But when it comes to RODS you can 'have a ball' lol.

If your gonna spend out for a balance job, then give them rods a good seeing too!

Always deburr the beams and a light polish and grind them balance weights off each end by at least 10grams smallend and 20grams Bigend...

I can get a sixpack rod down to the weight of an LY rod!

Just imagine how much weight you can get off an LY lol...

Why bother you gonna say now?

Less rotating mass is always good for any engine!
