Small block Chevrolet water pumps available from Tuff Stuff for short or long water pump applications in chrome or polished finishes.
Chevrolet used short water pumps on all passenger car applications thru 1968 and trucks thru 1972. Long water pumps are used on most later applications. If using a long pump we recommend the use of a 1972 or later pump, as they have reinforced bearing area, a larger impeller and will accept a 2 groove pulley. A LONG OR SHORT PUMP MAY BE USED ON ANY YEAR CHEVROLET V8 ENGINE. If overall length is a factor in your installation, changing from a long to a short pump will reduce the length by 13/8” on small block and 1½” on big block.
Short water pump crank and water pump pulleys must be used with a short pump.
Long water pump crank and water pump pulleys must be used with a long pump.
