    Interesting how little the lift is; no wonder it was rated at only 175(?) HP.
    But please correct the duration, I would like to know what it was at .050. :)

    Yeah you're right with the 175 HP (I am surprised with so little lift also), and yes can you please tell the duration at .050?

    The cam was the 3896929, 112 lobe sep, ground 4 degrees advanced. The other specs given match the old TRW specs. '79 should be the guaranteed-to-crack # '624 heads, which typically get replaced by the '882s. Should be 1.94"/1.50" valves.

    Best deal on that engine would be a set of Vortec heads with some 1.6 ratio rockers to improve lift on the peanut cam, set of headers. Feel the difference in the seat of your pants.
