Good morning gentlemen, quick question. I have a 360 in. (bored .060) SBM in my 51. The crank was internally balanced by the prior owner (a FABO guy!) so I have a zero balance front harmonic damper. I have an A518/46RH transmission behind it with a performance high stall converter. I am preparing to swap it with a low- stall converter which would be better for towing, this is a non-lockup transmission. It's absolutely a 46RH.
The big question;
Do I need a zero balance torque converter? I am asking, is the balance weight often found on the flex plate side of the torque converter part of the crankshaft balancing system?
In which case, I could simply remove the welds and the weight, but I wanted to confirm that this was not a balance for the transmission but instead part of the crankshaft balancing.
