At home flywheel balance....

You just have to have faith in your abilities, don't you :)
Yes, it would be good to have a different diagram available with a more common user friendly drill bit and location than what Mopar has ;) I read of members here taking their flywheels to machine shops just to be told they need to get a drill bit first before they can do the job.
Just to clarify, I won't be welding any weights to the wheel, I will be bolting one on , just like McLeod etc do. If I get really interested, I might design a balance plate specific to the 360 like they do for SB Chevs. Quicktime have them but they are not SB 360 specific.

I like the fact you are thinking this out, instead of commitment to a machine shop. Kudos, & good luck.
