360 BALANCING
I had a 74 360 here and it would make Chafing sounds at higher RPMs. It had a neutral balance converter and was out of balance. I am not sure how many miles but only in the car for a month. Driving , Tuning, Starting and reving it for friends.
We tore the engine out and discovered the trust bearing was wiped . The pressure from the converter was causing the counter weight to scrape the block. Replaced the thrust bearing after seeing there was no wear on the crank shell. Noise was gone. replaced the converter. Car never had the problem again.
My son balances engines and he just took a neutral balance flywheel and made a 360 external out of it using these blueprints. Any Machine shop can do this. using an indexer table and the correct taper bit.
