I would think the L79 would have come with deep groove pulleys like the L78’s. Although my ‘67 L78 actually just had a standard pulley on the alternator from the factory, so mistakes were made on assembly lines! To this day haven’t been able to find a deep groove water pump pulley for my ‘67 L78, so I opted for the standard pulley....hope it works.
I. Never threw a water pump belt back in the day, however I threw the power steering belt off a few times. This makes me wonder if the factory messed up by not installing the cast iron deep groove p.s. pulley as well!
Don’t you wish fan belts were as cheap today as back in the day! LOL! What did they cost...something like $1.75?
I will have to deal the belt issue when I get by build done....hope it’s not a pain! I also don’t like the sawtooth belts...smooth is the only way to go!
