Reaper® 538 Lever

Rapid acceleration and strong thrust for engines with large-bore cylinders, modified heads, intake, compression and exhaust
The Reaper® 538 grind excels in engines of 124" or more cubic inches with a higher compression ratio.
The standard throttle body offers excellent power delivery; the high-flow throttle body increases maximum power
No ported heads required, but they complement the camshaft and increase torque across the entire range
A high-flow exhaust system and air filter are highly recommended for optimal performance
RPM range: 2250 - 6250
Manufactured in the USA
Camshaft specifications measured on the engine on the lifter @ 0.050 using a 1.61 rocker ratio.
