I am thinking about swapping a bbc into my 81 Malibu. I am curious to know what is required parts wise and what needs modification to fit.
car is an 81 Malibu factory v8 with a/c and power steering. would like to retain a/c and power steering.

motor is bbc cast iron block and heads. my a/c box is the style with blower motor mounted on the top.

You're going to need an A6 compressor, all the brackets, pulleys & mounts unless you want to convert to a serpentine belt setup. They never used R4 compressors with V-belts on BBCs.

I don't really know of the lines interchange on the compressor. I've never tried the swap, but I do know the specs are different. The A6 line pad is listed as "2 inch gauge" & the R4 is listed as "1.2 inch gauge".

pull the small block out and pop the big block in.

Worst part about the swap is the exhaust if your using headers.
