5.9 Magnum flex plate too small??!?!?!?!?
A couple of things that I see by their photo and their ad. First, where is the ring gear? What engine is it balanced for: the 400/440 or for a 360? Maybe it's just me, but unless they can be more specific as to the application, I'd be cautious on ordering this converter.
From the description, it to me, is just a stock rebuilt converter, that would have the factory stall between 2200/2500 rpm. There is also no mention if they rebuild converters or just purchase them from someone like Transtar. JMHO
