The iconic MOPAR Wedge engines powered a wide range of Chrysler muscle cars. Names such as Charger, Daytona Charger, Super Bee and Challenger, from the Dodge Division, and Plymouth iterations such as the Barracuda, Superbird, Road Runner, GTX and more.
And even though the popularity of these engines dates back to the 1960s, by the 1990s MOPAR engines were more popular than ever, even though the last of the MOPAR Big-Blocks rolled off the assembly line back in 1978.
This hands-on book provides all the important information, with both text and photos, on how you can build your MOPAR engine to power levels of 600, 700, 800, and 900 horsepower.
Bring your MOPAR to the next level with the help of this book!
Book Excerpt: How to Build Max-Performance Mopar Big Blocks
THE OIL SYSTEM
"There were two versions of the oil pump from the factory. A standard pump was used on the majority of engines, and the high-volume pump was introduced for the higher-performance motors."
"The high-volume pump has both a taller gear set to pump more volume and a stiffer relief spring to increase the oil pressure in the main gallery at higher engine speeds."
"You can retrofit the stiffer relief spring to the standard volume pump as an easy way to increase oil pressure."
"The question about which oil pump to use often comes up during bench race sessions. There are a few general rules to help make the decision. Most big-block Mopar engines are going to be happy with at least 20 psi of oil pressure at a hot idle and maximum of 80 psi at wide-open throttle (WOT)."
