That may be a 361 Edsel motor, and not necessarily the truck version. Here is a photo of a 1959 Edsel Corsair with the 361 motor. All of the big block Fords were known for having lots of torque. Either way, great boat motor.
Edsel 361 engines were assembled in Cleveland, OH. Standard for 1958 Ranger, Pacer, Villager, Bermuda, Roundup, and optional for 1959 Ranger, Corsair, Villager.
