S&S 540 and 590 Torque Cams for Big Bore M-8 Models

 S&S 540 and 590 Torque Cams for Big Bore M-8 Models


As a follow-up to its 50-state legal 475 cam/calibration for M-8 Touring models, S&S Cycle, the  Viola, Wisconsin based masters of 'Proven Performance', has released 540 and 590 torque cams for Big Bore and even bigger Big Bore M-8 models.
As a next step, the new 540 torque cam for Big Bore M-8 models is designed to work with 124" and 128" big bore kits and produce "stump pulling torque" down low in the rpm range as well as maintain respectable horsepower numbers

Available in gear or chain drive and in a complete cam chest kit with pump, plate, pushrods and tappets, you can check out the dyno charts for the 540 online. S&S is citing an impressive 130+ lb-ft on a conservative 124" build!
The S&S 590 cam for even bigger bore M-8 models "is capable of making massive power! It happily accepts big bore kits, stroker cranks and, of course, high lift cams."

The primary supplier of that sort of go-fast stuff is S&S Cycle of course, and the new 590 lift cam is designed to work with the 131" stroker kit and other huge bore combinations. "Producing massive horsepower, especially in the higher rpm range, the 590 is available in gear or chain drive and is specifically for use with monster bores, ported heads and high rpms to make maximum horsepower. Not recommended for stock bore engines!"
You can check the dyno charts for what S&S has seen this cam making online, but the company is citing 146 hp and 145 lb-ft torque on a 131" stroker build.
