Hey guys I am planning on converting my 67 300 to a four barrel. I already have the intake for it and I was just given a virtually new holley 600. The problem is that it dosn't look like the holley will fit on the intake. I seems as though I am going to need some sort of an adapter. Is there any one on the board running a holley carb on a stock 300 intake. I thought since the rodchester and the holley were both square bore carbs the had the same mounting flange but I guess not thanks for the info. thanks Adam
