Our water pumps are manufactured by AC Delco, which has the reputation of making long lasting and reliable parts. The Short and Long of Chevy Water Pumps Nova mechanical short style water pumps measure 5-5/8? high from the shaft down. Long style Nova water pumps measure 7? high from the shaft down. An easy way to find out what style you have while your pump is still installed on the motor is to try and stick your hand between the water pump and timing chain cover. If you can slip your fingers in between, then you have a long style pump. If you cannot, then you have a short style pump.
