Good for adapting a Holley 4412 to a 4 b

March 02, 2015
I have purchased and still use two of these adapter plates to mount a Holley 4412 onto a stock SBC 14096242 intake to meet local Street Stock racing rules. This is the cast iron copy of the Z-28 High rise manifold. The plate works well for this purpose but you may need to modify the outer slots to make them wider. Example: to mount this plate using ARP 200-2401 studs instead of the provided Speedway 13560 studs onto the 14096242 manifold, I had to machine the slots out to allow the plate to fit over the studs do to dimensional interference caused by the slots being too narrow and/or off center to the SBC stud mounting holes. Note; this may be an issue only on this exact manifold and/or only when using the ARP studs, but this has been my actual experience. I purchased my two adapters 5 years apart in time and had to perform the same modification to both. It is a good product, but don?t be surprised if you need to modify it slightly to work on a stock SBC manifold.
Yes, I recommend this product.

No this will not, however adapter part number 1351934 may fit your needs. Measure the bolt pattern on your intake manifold to be sure that it will fit.
