I am still trying to find out all the particulars with bolting a 273 intake onto a mid 70's 360. If all I have to do is ream out some bolt holes that will be no problem. No one seems to have a 100% clear answer so far.
i think if i have understood it all right that the "pads" that the bolts sit against on the intake may be machined at a diferent angle also, i bet that could be adjusted with a mil quickly, hope im right on this
