I am getting closer to the end of a 360 LA project.

Long story here. So my quick question is, Has anyone ever seen a A/C Delete Double Pulley for an RV2 Compressor?

This would let one remove the A/C clutch, remove the RV2 Cast compressor. And then bolt in the delete kit with double belt pulley, so I could add the A/C at a later date.

I could have sworn that I have seen these on some cars and truck late 70's to mid 80's

Any input would be greatly helpful, and maybe you have one in your Box O extra parts.

I know they used to make them for maybe late 70s or 80s cars.

Whether or not they still do I seriously doubt.

finding one would be some task , unless you get really lucky

i just sold this exact setup to a member here a couple of weeks back. it came from a 74 chrysler newport with a 400.
as the pulley setup was attached to only the water pump housing, it worked on his 440.
the same pulley arrangement was also used on trucks in the 70's, but i can't say the exact year range.

a couple more pics..........

I guess this later style for LA small block wouldn't work? I have one of these from '88 Diplomat Police. Sure looks different I know.

Larry that might be it. The only thing I need to find out is if that 88 Cop car had the RV2 compressor. Although I believe that it would have had the Aluminum style C171 compact A/C and I see that Bad guy hauler has the 100amp alternator. So that large bracket is special to those parts. I will send you a PM. Thanks PLY 478

Sorry it did not have the RV2 it had the crappy round one I just thought someone might chime in and say there's a way to use later idler pulley and they've done it.

I knew I have seen these on LA Engines.... With a standard 60 amp alternator!

So probably '79 back to ?

Or an 80s 318/360 vehicle that has the old style alternator. They still use the older style alternator bracket not the big one that wraps around the passenger side of the AC compressor.

But would that work because it was not the RV2 a/c?

Last year for the Rv2 was '79 I believe. I don't think the round '80 up compressor brackets would work. I've seen the idler setup on a few 70's trucks as pictured but don't recall seeing them on a car.

79 was last year for the RV2 and when they changed compressors they all changed the intake. Had to move the thermostat location a little bit to clear.

A/C delete idlers on 70s cars are pretty uncommon - I mean how many non a/c late 70s cars have ya really seen? A bodies sure, but extremely rare on B and C bodies. Best bet here is find an factory parts book, look up the bracket numbers, start messaging people on FB. I hate to endorse that place but it's the new go to and where I found the idler setup for big block truck water pump w/o A/C. Oddly enough, at least part of that setup was also used for mounting air pumps on big block C bodies.

I just sold a 78 non-a/c bigblock Cordoba I had bought for parts. I could ask the buyer if he'd let that piece go.

He's looking for small block bracket.

I have the pulleys/brackets for a/c delete off of a 88 B150 318 TBI intake IIRC. but fit the late LA 4v intakes with sanden comp.

it used the small alt with a jack-bolt to torque the belt. big brackets and would use a sanden comp. complete set up and has a bolt on idler pulley and bracket in place of the comp unit. TBI = fuel pump block off plate

even these mid-late 80s a/c delete brackets pulleys are hens teeth when you need to replace just the idler pulley/bracket.


I want to say that the small arm/pulley that bolts to a/c brackets are the same SB to BB just the brackets are different. I will have to have another look in the shed and see if it looks like the pics posted IIRC it has 3 bolts?

I may have a single a/c delete pulley that came off a 440 c-body no a/c or it is an idler pulley for a/c???
