|540 torque cam for Big Bore M-8 models|
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."
|590 torque cam for 131" M-8 Stroker kit applications|
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.
