Choosing a stall speed.

I don,t think they would,ve put a 360 converter in it(external balanced)with your 340 being internally balanced.They might,ve put a 318 converter in it?You should be able to order a 2500 stall from your local trans shop.Converter Man is in the Toronto area.I had a 2500 stall from him behind a 360...worked great.
