73 340 external balance factor

We need a answer for a cast crank 340/904 trans....


B&M no longer makes the cast crank 340 to 904, unless you find a used one. But the 340 cast crank to 727 will work, has both sets of mounting holes for converter, it's just a little bigger and sometimes the started hits it, using a newer starter off a mid 90's magnum solves that problem or a little grinding on your old starter. I am using one on my cast crank 340/904 combo.
