    Finding specs on existing cam
    « on: March 11, 2010 - 03:47:35 PM »
    I am rebuilding a 340 and I have a Voodoo hydraulic on the way. Is there a way to figure out the specs on the cam coming out?

    Look on the Lunati site for the part number you bought

    Sometimes the part number is on the end of the cam, either stamped or engraved. If it is there, try google or post here....

    You need a degree wheel & dial indicator.   :thumbsup:

     :iagree:

    If you do the degree wheel thing, total advertised duration is actually measured at .003 (.002) of valve lift so you'll need to divide by 1.5.  Same for duration at .050 (.033).

    LOL...Sorry, somewhere between reading the title and reading the question, I jumped from the old cam to the new cam coming to you.  I am the goober :) I would guess that it may have the number stamped on the rear end of the cam, but, if you are like me, it probably will not.

    If not, then using a degree wheel and measuring lift points at the lifter will give you the closest info as others have said...
