Default 6.2 engine torque?

The 6.2 merc make 320 hp, but I can't find it's torque rating. Does anyone know this and how it compares to the 454 mag & 496 torque ratings?

I ran a set of 6.2 on my dyno they were bored .030 383 cid had eddie marine exhaust with long risers made 350hp and 400lb of torque,the big blocks make more torque but also have more weight we have done several repowers taking out 454-330hp and installed 6.2 and the boat ran about the same needed to put smaller prop and let the engine rev up to 5k for it to work right

^^^ Good info there. I have also wondered that same thing that the Greg posted. Im guessing the 6.2 would get a little metter milage vs the big block also.

I did a quick search on the Web and easily came up with 320 prop shaft horsepower but could not find a torque rating.
I have twin 6.2s in my Fountain. It is a pretty light boat. It easily gets on a plane even with a full load of passengers and fuel. I would think deciding between the 330 h.p. 454 and the 320 h.p. 6.2
would depend on room in the bilge and the weight of the boat.
