    It should work. I know all the aftermarket manifolds are listed for engine sizes 265-400sbc.

    the only thing that will be diffrent would be the plug numbers on the manifold correct?

    it depends on what heads, TBI, Vortec, or just plain carb heads. the bolt pattern is different on all 3.

    400 plug numbers are not different lol

    same deal 55-90's cept that in 87-90 some are TBI others are still carb(changeover years) and the center four intake bolts changed the angle they are drilled and tapped
    but there is an easy work around for this

    put the intake on, you have nothing to worry about

    good luck
