The Short And Long Of Chevy Water Pumps

Chevy Nova mechanical short style water pumps measure 5-5/8” high from the shaft down with the pilot shaft diameter measuring 5/8". Long style Chevy Nova water pumps measure 7” high from the shaft down, and the pilot shaft diameter was 5/8" as well. Do not mix and match pulleys from short and long water pump engines because this will cause pulley misalignment. An easy way to find out what style you have while your pump is still installed on the engine is to try to stick your hand between the water pump and timing chain cover. If you can slip your fingers in-between you have a long, if not you have a short.
