    Don't know where to find the specs, but you can bet they're weak. [​IMG] The factory manuals show the amount of lift, but not the duration. [​IMG]

    Old Chiltons that covered large blocks of years, like 1969-1979, and all domestic vehicles, show the engine specs, including cams. Don't have easy access to them, but someone here must have one laying around. Thats about all its good for, has engine HP and torque specs as well. Then again, it lists the 327 as having the wrong bore, so you can't believe ALL the book says.

    Why insist on counting when the ring gear has the tooth counts stamped in?

    Actually I'd check the library. The Chiltons I see at auto parts stores now seem to be specific to one vehicle (like 73-87 trucks) so comparing engine specs or something versus a car or another make isn't possible. If they have them at the library, you could photocopy the pages.

    Hmm, '77 was about the height of emissions insanity. Around that time, the engines were so weak that you were lucky the valves opened at all. [​IMG] I think that's around the year that Corvette's came with a 160 HP 350. [​IMG]

    I have a Chiltons that covers Chevy Trucks from 88-90.
    Here's all that's listed under camshaft specs for an '88/350:
    Journal Diameter: 1.8682-1.8692
    Lobe Lift: Intake - 0.2565, Exhaust - 0.2690
    End Play - 0.004-0.012

    Sorry, that's all that's in the book :(

    This site may help....
