superchevy · 03-19-2005, 11:24 AM

I want to swap a 454 into my '81 Silverado, but want to use different, wide-mount Alan Grove brackets for the A/C comp and alternator...the stock R4 radial compressor will not fit these brackets as they're designed for the Sanden 508 compressor.
Question I have is, besides having new a/c lines fabbed-up, is the Sanden compressor compatible with the rest of my stock a/c system?
Thanks for the help,
SC
