So I’m doing a 455 swap into a 71 GS 350 with factory AC. What do I need to make it all work on the 455? Any help is appreciated.
I use my 1970 350 brackets on my 455. Fit fine. Aluminum base and the metal top. On the power steering I used the 1973 bracket the pump was on from donor engine. I think the aluminum 350 bracket might work but at time did not try. Using the 73 455 pulleys if I remember correctly as I also have a 71 core engine but is preserved in oil sludge. Many parts interchange I found. My 70 is an early car 11/69 build if it means anything.
