  •  Reaper cams are specifically designed for 80 - 100" motors utilizing 3 5/8" bore and strokes 4.5" to 4 5/8" stroke and airflow exceeding 270cfm. These cams need 11.5 or higher compression to build proper cylinder pressure of 190psi -230psi for best street performance.



    All Reaper cams are available in mild, medium, hot and Very F Hot lobes.
    You can expect power and torque increase with each step up in lobe and
    ramp design.
    Hot and Very F Hot require a Hydrosolid or Solid lifter.
    These cams have the hottest and fastest ramps on the market and will put any comparable cam to shame.

    There are many more cams to come, we custom grind each cam to each customers specific needs as one size does not fit all. All cams are ground on billet cores and take 6 to 8 weeks from order to get.
    Custom Ground Reaper with Gear $390.00
