How's the tension. Properly adjusted?

It is the pulley's. My 351 was also going through belts. The 351 is a
marine engine from Ford and Red Line Marine in Lewiston, ID is a parts
distributor. The pulleys are only one the marine engine. Red Line ships,
the pulleys are not cheap. Pull the pulley's and check the numbers on them.
They are stamped in to the metal.
