anyone know how to tell the stall speeds of factory converters? i have the following good converters: 84 truck 360/727, 79 cop car 360/727 and a 73 360/727 truck. all are good converters. want something around 2000 for my 77 shortbed that is getting a mild 360 in then ext few weeks. i can buy them for around 200$ but if i am only getting a few hundred RPMs of stall, will it be worth it? Can you determine the stall by the diameter? if anyone has a converter around 2000-2400, i would be interested. thanks, JP in KS.
