1966 Valiant Sedan V8 Swap (Victoria)
I dont need no stinking external balance. Prefer to not deal with it. Makes my life a little easier if i dont have to think about that part of it. I am assuming the B&M flexplate with semicircle chunk missing is part of the balance allowing a neutral torque converter without a welded on weight.
I am having my rotating assembly balanced internally on a machine, then having my machinest install the flywheel and harmonic balancer and spin it again to balance the flywheel and the harmonic balancer as seperate items balanced to the crank.
