Other than the factory 301 installations, is anyone running a Pontiac 350, 400 or 455 in one of our cars with working A/C? I'm looking to start gathering parts to make it happen. Not sure whether 301 brackets & lines can be modified to work, or if I'm better off using the old A6 compressor somehow with custom lines. I imagine parts for the R4 set-up would be easier to acquire and fit without trouble. I'm open to suggestions too.
