I just converted from a 350 to a 455 in my 72 skylark convertible, is the ac compressor bracket the same for a 455 as a 350.
I'm no expert and don't have an AC car but I believe it is essentially the same though you may need a different adjuster arm for the alternator. When I went from a V6 to 455 in my 75 Skylark, that was the only issue I had. Other than that, it was pretty straight forward.
