Coan converter opinion

Got a Coan-40320 10” max performance converter. Any opinions pro or con?
Engine is approx. 600+HP with Dana 60 and 3.73. Thanks
Good product. Just hope if it's used, you know the history of it, and the owner. It might also be a good idea to contact Coan and give them your engine specs and see if it is the right converter for your car. Just because it worked in another car doesn't mean it will work worth a damn in yours. JMHO
