107 bolt on performance kit.

featuring our all new HQ-TC-540-HC camshaft especially designed for this kit.

107 Kit

Bolt in power to upgrade Twin Cam 96 inchers to fire breathing 107 cubic inchers with no head work or other parts required. All that is required is boring your stock cylinders, reassemble, tune and go. NO head work required. That’s right. Your stock heads can stay as they are and continue to use the stock valve springs and other hardware. You will not need to purchase adjustable pushrods or any other parts except a few gaskets. We recommend a good exhaust system like the Supertrapp S2-1 Supermegs and free flowing air cleaner and a speed density tuning system like SEST, TTS or Direct Link.
Compression 10.5:1. Cam specs = In .540
" 20/46 x Ex .510" 52/20.
Cylinder bores will need to be finished to 3.938
