Balance shaft delete

[77amc]

I did mine and it was a SNAP! Only felt a slight shake at under 800 rpm's

I have a guy here that can balance to ZERO if you want. (2g is a penny) BUT He's 200.00, and another place (Bullet cams) charges about 175.00
Well worth it if you ask me, and guy one is going to do my 4.1 Buick V6 (they can be a challenge)

Jasper does it to save on $$ each engine that needs a balance shaft.

That's pretty interesting that a racer builds an engine with excess rotating mass that the engine doesn't need..
Usually they go to extreme lengths to make EVERYTHING as light as possible.

I wonder how much out-of-balance weight it takes to produce noticeable shake/roll at idle, and how much that amplifies into wasted engine power at speed? The machinist who balanced the crank most recently said he drilled-out a 17g correction, which he seemed to think was quite a bit.
