Looking to help a friend out, he is unable to measure the cam specs on his own. He has an earlier FE camshaft, solid flat tappet, Marked as a 306 Revmaster and has X74 on the end. Anyone have an old catalog that may know all specs? Thanks in advance
From my '76 catalog: 306 MECH Revmaster Intake 39-87 Exhaust 87-39 Lift .532 Valve lash hot .024 Duration 306 No reference found to X74.
Thank you sir! Would love to know .050 numbers but my guess is it was made long before that was common place. The lift and cam timing alone helps greatly, showing 114 LSA ground with zero advance
The .050 numbers came later, as the info above is all they provided at that time, and that cam isn't included in my 2010 catalog. You may want to contact Isky for possible additional specs.
