Produces a wide powerband that increases torque and horsepower throughout the entire RPM range
Direct bolt-in replacement for M-Eight engines; can be used with stock valve springs, pushrods, lifters and exhaust
Will respond well when used with slip-on mufflers or full exhaust system and a high-flow air cleaner
Fueling recommends mufflers with smaller cores for the best low-RPM power
