Water Pump Pulley/Fan Clutch
« on: February 14, 2019 - 04:24:29 pm »
I have a 74 360 engine that had A/C and P/S. When I bought the engine the water pump pulley was missing. Does the water pump pulley for an A/C car supposed to have one or two grooves? I plan on reinstalling the A/C.
Also, is a fan clutch better than a direct drive fan? This is for a daily driver.  Thanks

An AC car should have 2 grooves.

Thanks. I wasn't sure since the pulley along with other parts were missing when I got the engine.

If you spend some time searching the internet you will find pictures of assembled engines with AC you can use as a reference. Small and big block are similar yet distinctly different is bracketry and positioning but will provide the overall concept.
