1999 Indian Chief:
The combination I am running is the S&S 88cu.in. EVO, with the Thunder Jet carburetor 3rd circuit upgrade, Crane HI-4 Ignition, White Bros. E-Series exhaust 13 discs, and the S&S 561 camshaft. This motorcycle is a blast to ride it pulls like a Freight Train. The bike has been dyno tuned. It has a Max HP of 92.6 & Max Torque of 90.5. At 2700 rpm the bike has 82 ft lbs of torque, max torque comes in at 3400rpm and pulls to 5000 rpm. Great combination.

The cam works great with SS heads and pistons. Dyna or FXR it is really a hot engine. On the lighter bikes low end is good. Wish I had the dyno info for you....
