I asked a Holley rep to recommend a carb for me, I told him I put a new distributor, 57 manifold  on my 55 Fairlane v8 272 y-block and he recommended a 0-8007 4 barrel 390 cfm so that's what I bought, I have had a terrible time to get the carb right, he vendor I bought it from just told me to send it back and he would refund  my money.
My question has anyone on the forum used this carb with a 272 with a 57 Ford intake and ha success with it? When I price this particular carb and put in a 55 or 57 Ford it states this carb is not compatible with the car. Someone please help if you can.
God Bless.
