Thanks David...
I'm probably going to go the route of speaking with someone at Comp Cams, Crane, or Edelbrock to determine which cam is right for me. Although, the stock cam for the 260hp motor is looking pretty good.
After viewing the specs of my 290hp motor and the 260hp, I see that the
260hp version does indeed produce more peak torque. Not surprising.The two engines have the same heads, compression ratio, valve size, etc... But while my cam specs out like this:
Lift/Duration - .450"/.460" / 222=B0/222=B0
The 260hp cam specs out like this:
Lift/Duration - 0.390" / 0.410" / 195=B0 / 202=B0
Seems like a better choice.
I understand the lift, but the duration has me stumped. Is that the duration of the time that the cam is at rest (valves closed) or something else?
