Yeah that will work if you don't remove too much.

Zero balancing a Flywheel
I'm putting a ZF5 behind an internally balanced 460.
Does zero balancing the flywheel need to be specially done or would an angle grinder or metal lathe and being careful not to remove too much work? I do metal work professionally, just don't have a balancing machine.
If my understanding is correct everything is balanced to have that externally balanced weight balanced with the rest of the wheel properly, so if it's gone the wheel should still be balanced, eh?

If it's a stock crank than it's a good idea to get it balanced if any part of the rotating assembly is changed. I just had my stock Windsor rotating assembly balanced because of piston and rod changes. I used a local reputable machine shop. Cost was $160 with a polish.

My engine is internally balanced. Clutch parts for the ZF5 are set up for externally balanced engines. Getting the bolt patterns, size, width, ect to match up is a pain and a bit hit or miss as there isn't much information out there.
Getting an externally balanced flywheel for a 460 that fits onto my '71 460 and having that work with the rest of the clutch parts and the ZF5 and just having to zero balance it is much easier than trying to find something off the shelf.
Not to mention a whole lot cheaper.
I may trim it down to help with the cost and then have it professionally balanced.
Thanks for the help.
