    I've searched and haven't been able to find the stock cam specifications (lift, lda, etc.) for my 1989 454 Bravo spec'd at 330hp.
    Anyone with advice on where to look or what the specs are?

    Both the MK1V and Gen 5 list the same cam. Lift int-.461 and ex-.479
    Advertised dur int-.350 and ex- .352. This is all the info the book gives. no LC. Hope it helps.
