Make sure you use '78 or older fly wheel. Starting in '79 they exturnely balanced the 460 429 and 460 before '79 were internally balanced. I used a fly wheel off a '92 460 had it nutral balanced and then put it behind my '73 460

you can also get one from behind a 370 engine that came in buses and dumptrucks but the bell housing will be harder to find than the flywheel. the 351m bellhousing will bolt behind a 370/429/460 but the flywheel will hit the bellhousing and depending on your flywheel thickness you may or may not be able to clearance it enough to work. L&L has a special clutch and flywheel you can put behind it to work but it is pricey, I got a stock clutch and flywheel to work but it took 2 days of head scratching and grinding to make it work.

if you find a flywheel but it is not a zero balance like the older models you can have a machine shop take out the counter weight with a little machining.
