My service manual lists the intake cam lobe lift at .252" (.436" valve lift based on 1.73 rocker arm ratio) and exhaust lobe lift at .278" (.481" valve), but the specs don't list the duration.

Does anyone know what the stock (truck) 460 cam's duration is?

Just wanting to know how much difference a stock cam and a "RV" (or cam spec'd for 4x4) have. I'm assuming not much.

Thanks.

193 / 206 @ .050" 113 lobe sep in at 110 ICL when straight up (early)


All bbf cams excepting PI CJ and SCJ have basically the same specs even the EFI engines.
