If you take a 302 HO and put a 347 Balanced rolling assembly in it, does that
change the stock external balance of 50 oz , as far as using the original harmonic balancer and the flywheel ?

A rotating assembly can be balanced to any amount, from zero (fully internally balanced) to any number including 50 oz and even beyond (though that's rare). Only the folks that balanced your assembly know what it was balanced to. Normally, you get a balance sheet with all the info. If you didn't - ask them.

Most the kits are balanced to 28oz. If iit was you will need the balancer and flywheel for a 28oz.

Thanks , I finally got I touch with the guy I got the motor from and he did say that the crank and flywheel were ballanced to 28oz and has a 28 oz harmonic
ballancer on it.
Thanks

A Balanced Kit will say if its 28 or 50 , even 0 . imo a 50oz 347 is trouble waiting . 0 is best

forgot , just ask the vendor/seller
