    Have any of you guys run across a carb adapter plate that will mount a Holly 4160/390 cfm square bore to a stock Buick 215. The intake is a spread bore. The stud layout on the manifold is rectangular (approx 4.2 x 5.6). Thanks for any help.

    DEADMANSCURVE my first word : truck

    you have a pic of intake opening ?
    I've got a couple older adapters , one may be ok ? will check .
    found a couple pics . one has some measurements on it . the 1.4" and the 1.67" are opening sizes . the other's should be center to center .
