Water Pump Options for the Chevy Crate Engine

Add Article To List

In this Tech Tip, a customer asked for some recommendations on water pumps for his 1934 Chevy Coupe build.

“I'm building a 1934 Chevy coupe street rod. My engine is a newer (1996) Chevy 350 small block crate engine with composite timing cover and vortex heads. Not sure which generation engine I have. Due to space limitations, I am looking for a short style water pump that will fit and the composite timing cover. Please provide me with some part numbers for water pumps that will work. I would prefer an aluminum and/or chrome water pump. Thank you, Duane”

Hi, you inquired about a water pump for your small block Chevy Crate for your ’34 Coupe build. There are a few options to choose from. In aluminum we offer P/N 91015582, but you’ll want to check your pulley as it has a 3/4" fan snout. We also have P/N 91015577 which has the more standard 5/8” fan snout and is also available in a polished finish, with both having 1" of clearance from the back to the block for the timing cover. If you want a custom pump we also have P/N 91015565 in a polished aluminum finish with roughly 0.88” clearance from the back of the pump to the block. Feel free to visit us on the web at or call 1-800-979-0122 with questions or to place an order.
