Ballancing a 1973 340

The Australian A Bodies used the 9.5 in flywheel we had in our early A's. I might be mistaken. You will have to count flywheel teeth or measure your clutch/pressure plate. The specs for the external balance on the 73 340 flywheel is known and can be verified and modified by a competent machinist. What does your front damper on the 340 say? Can you post a picture? Do Australian 73 340's have a cast crank? See Yellow Roses post. The next problem will be the Borg Warner 4 speed behind a 340...
