Zipper’s Twin Cam® CVO Muscle 113 Kit

What could be better than our Muscle 110 kit?
Adding 3 magical cubic inches to it, of course! By adding .060” to the bore and 2cc’s to the pistons, a sweet spot was identified, and the Muscle 113 was born – with nearly 11 more HP and 9 more ft/lbs of torque. The Muscle 113 has a very similar power curve when compared to the Muscle 110, just more of it, everywhere. 50 more horsepower and 42 ft/lbs of torque than stock! Zipper’s Stage III CVO CNC porting, proprietary +12cc pistons and Red Shift 657 cams provide everything needed to produce the power. Upgraded valve springs and Red Shift Dual-Piston tensioners with Pro-Taper pushrods add stability and life to the unstable factory valve train, up through 6,500 RPM.  Big Power awaits the CVO owner with this powerful top end and cam kit! M8 owners will respect the Twin Cam® Muscle 113!

CVO engines are known for lifter and oil delivery issues, so our 417-498 blueprinted cam chest upgrade is highly recommended.

This kit uses your factory head and cylinder cores sent in for modification.
