Keeping Your Cool
|
The water pump on the left is from an original, '69, small-block 350, and the water pump on the right is a brand-new Edelbrock Victor series water pump. The stock Chevy water pump's impeller may have kept the original 255-horse 350 cool in '69, but if you're making more power today, consider the Edelbrock unit. Inside, the Edelbrock computer-designed pump passages are designed to flow more coolant with a higher velocity, even at lower engine speeds. The Edelbrock impeller is CNC-machined and differs tremendously from the 35-year-old original design. View Related Article
