Harbour City HD – How Much Lift ????? 186hp / 186tq

Putting our theory to the test – How much lift is really required with the M8 4-valve cylinder heads

Pump fuel 143ci build with Cycle-Rama, Inc/APE CR500 Magnum cam.

186Hp/186tq

Sure, these ported M8 cylinder heads move a huge amount of air and the peak CFM numbers are very impressive… But how much do you really gain by installing a cam with .580″or more lift.

There will be many varying opinions on this topic and we’re 100% fine with that Putting our theories in to practice is the only way we can continue to develop & learn though.
