I'm putting a 1970 460 into an 86. I can license it as a 1976 model. I would like to find brackets to put saginaw PS, and AC (not R12) on the motor with no smog. Can anyone help me out with identifying the brackets I might need?

 

I pondered this swap, and looked at several ways to do it. The most important part of it is this: You MUST ABSOLUTELY use all the pulleys and brackets from one setup. They will not mix and match.

1. Use the brackets and pulleys from the '79 and earlier engines. The A/C bracket will be for the square York/Tecumesh compressor. There are adapters which bolt to this shelf-like A/C bracket to allow you to use a round Sanden compressor.
However, if you use the setup from a '77 or earlier, you will find it necessary to use the earlier PS pump, the round cannister kind. '78 and '79 allow using the wide mouth plastic body pumps. (Note: You can use the later pump and later brackets on an earlier engine and PS gearbox, just change the pressure hose to fit the pump.)

2. Use the setup from an '80 - '86 or '87 non-serpentine system. This is a complicated pulley setup, with lots of intermediate brackets and all, but will allow you to use the Sanden compressor, as well as the larger plastic bodied P/S pump. These are cast iron, and are heavy.

3. Use the dual belt serpentine system from an '87 or later 460. You can use the Sanden compressor and the later PS pump. Ther are only 2 large brackets and they are aluminum. The one additional bracket is stamped steel, and it is the alternator adjustment bracket.

When I put my '86 460 into my '66 F-100, I used option number three, and bought the aluminum brackets. The alternator one is available from Ford, and the A/C-P/S one is available from several obsolete parts houses advertised here on FTE. I scavenged the pulleys and other parts from a wrecked '89 E-350 van with a 460. I couldn't use the van P/S-A/C bracket because it was the wrong pump (flat GM style), and the alternator bracket on the other side was cracked.
However, all the pulleys and other parts were all there.
I used my '66 alternator with the '86 alternator fan, fan spacer and alternator pulley.
I used a shorter alternator belt to bypasss the unused smog pump.
I couldn't use the '86 fan, it hit the upper radiator hose, but I used a fan and fan clutch from a '78 with a 400.
I used the '86 thermostat housing, with the '86 upper radiator hose cut a little shorter. (The '70s housing didn't allow the hose go over the alternator, it made it try to go through it instead.)
I used the '86 Sanden compressor, the '86 serpentine belt tensioner, and the '86 PS pump.
However, I had to get the serpentine PS pulley off a '92 Bronco with the same PS pump; the flat GM style off the wrecked van had a different shaft hole size.

Be aware that if you try to use '80s bolts on '70s heads, you will find the bolt hole threads to be smaller on the earlier heads. You will find it necessary to turn the bracket bolts down, and re-thread them.

Hope this helps.

 

Thanks for all the information. I've been eyeing the van PS set up so that I can use the GM style flat PS pump. Those pumps put out more pressure at idle than the Ford can or big mouth styles. Lots of 4x4 rock crawlers switch over to this pump. I'm setting my truck up for stump pulling torque and towing. I'm switching to a 5 speed to help with high way rpm with the steep gears.

I was hoping I could find (in my dreams) a listing of Ford part numbers for the brackets so I could see if they still carry them at Ford or one of the obsolete part houses. I don't hold out much hope of finding a pre 79 van with a 460.

I'm planning on using the standard multi-belt pullies and try to switch over to the single serpintine belt.
