I have been searching all over and can't find a conclusive answer. My pump is on passenger side and is the short pump R4. What bracket do I need to mount it to sbc 327?

Should be any A/G with a SBC & most '77 to about '86 B could donate the OE set up as long as you have '69 & newer heads with the accessory holes. A way to keep the compressor on the passenger side the B & F serpentine set up should be what you need to keep iy there. A;ways remember to get all related hardware, accessorys & p/s pump core to ensure you have everything you'll need. Some have used the S10 4.3 serpentine set up.

My passenger head has only 1 accessory hole. If I cant find this stuff at a junkyard can I order it online anywhere? Chicago Muscle Car parts has it but its $325

Most 327s in stock form will not have the accessory holes in the front of the head like this.

If there are no holes you would have to fabricate something.
If it is the last couple of years of the 327 or the heads have been changed to ones like this.

then you can use any of the later bracketry for the R4 compressor.

You're good, your heads are the '69 & up set up. The Driver side should have three.

Yeah driver side has three. So I gotta try to find a v8 gbody at junkyard otherwise start searching online for the oem v8 brackets? And then I can just use any other sbc brackets for alternator and steering?

Even those B bodies I listed & about '78 to '81 Camaros can be a source. During this time period all SBC powered passenger cars used the same bracket set up with the R4 compressor. Keep in mind the OE SBC set up you'll need new lines.

SBC has R4 on the driver side in a G-Body. You could use serpentine 3rd gen Camaro F.E.A.D. and keep the compressor on the passenger side.
