S&S Cycle - M8 Cam and Camshaft Chain Kits
This new HPT542 M8 cam is a direct bolt-in for non-VVT 117-121 ci engines with oval port heads. Described as delivering a "strong, flat torque band" with an "aggressive lope at idle" it is a "big power" cam for Gen 2 M8 models that has "the sound of something ready to perform, and when you open the throttle, you feel it."

The "mile-wide" torque band and high rpm horsepower comes from the .542" lift at 1.64:1 compression ratio that pulls from 2000-6200 rpm. S&S says the HPT542 "works great up to 11.7:1 compression and is compatible with Gen 1 M8 engines using S&S .605" lift springs (performs excellently with a mild port job).
"We have seen outstanding throttle response with this cam and the aggressive lope at idle is still remarkably streetable".
