I have a 239cid OHV Y block and I want to put my 2bbl Holley in place of the original 2bbl bottle neck. I don't know exactly what size they both are, here's a picture of the one I want on this motor in the end.

I have the intake for that carburetor but it was from the 272 Y block and I noticed that that intake is different than the one from the 239. So I am looking for an adaptor plate to go from the 3 stud bottle neck carb. to the 4 stud Holley. I have spent a couple hours looking for one but I have been unsucessful. Does anyone know if someone makes one.
I should also ask would it be fine running the 239 with the Holley?
Thank You.
