You guys have been a great help so far, and I've run into another snag. In swapping my engine for this Lincoln 460: I was mocking up the AC brackets yesterday to use the 84's stock FS6 compressor. I quickly found out the water pump on the Lincoln motor (69) interferes with the bracket's ability to bolt to the pump. Apparently the snout became longer on the 70 and up water pumps and maybe the angle of the water pump hose connection is different too?? Anyways, I'm thinking I have to change the pulleys out to something 70 or newer and am guessing I will be using a "bolt-on" crankshaft pulley as well as the appropriate water pump pulley.

The alternator will have two belts, no smog equipment so just P/S pump, AC compressor, alternator and water pump. That leads me to my final questions: I'm hoping I can use a crank pulley and water pump pulley from a 70/71 Mark III, and where can I find the power steering pulley for an 84 F250 equipped with a 460 stock because I imagine that is what I'll be using for a pump. Finally, in using the 84 pump, will the pulley line up with the water pump pulley or crank pulley from the 70/71 Lincoln. If the Lincoln pulleys don't work, what has someone done who has used a Lincoln motor for this swap and has A/C? Any pulleys I can find aren't cheap and I'd rather have a good idea of what will work before I buy them - 2 or 3 sheave crank pulley or 2 or 3 sheave water pump pulley...,

Thanks!!

 

Since you'll be in there swapping stuff around anyways, avoid the CII power steering pump and upgrade to a Saginaw pump. Saginaw Conversions - Gary's Garagemahal (the Bullnose bible)

 

You are getting ready to open up a real can of worms here. Mixing matching pulleys can become a real problem sometimes. You need to proceed carefully. The engine you have now has everything on it that you need, all the correct pulleys and all the accessories you need except the proper A/C bracket? Is that correct? Did it have any type of A/C bracket already for an older style compressor?

I am not too familiar with the 429/460 engines. Can you swap lower pulleys I am not sure. I know on the 302 around 1970 they went from a 3 bolt pulley to a 4 bolt pulley. And they had different waterpumps also. I know it can be a real mess on the 302, but not sure on the big block. If it would interchange, the only option I can think of is putting a truck 460 engine dress onto the old 429, but not sure if it would all work out.

 

I am beginning to see this LOL. Part of me wants to embrace this challenge and make it work, the other part of me wants to say to heck with it and just use all of the original components. More on that below.

This is basically the whole hang-up: the AC. So the engine came out of the Lincoln complete. It's a 69 engine which has it equipped with a crankshaft driven power steering pump. My initial intention was to use the original belt drive but install the AC brackets off of an 83-86 F250 originally equipped with a 460 so that I could use my FS6 compressor and lines (that I just spend a ton of money on to have reproduced). The issue I ran into yesterday while mocking it all up was the water pump gets in the way, The whole pump apparently changes in 70. So I'll just install a 70 pump, right? WRONG (so far as I can tell). Looks like everything changes in 70- balancer now has a bolt-on pulley, now obviously the water pump pulley is different, timing cover is different.

So I'm looking for someone who has swapped a 69 Lincoln motor into an 80's and not only retained air conditioning, but used the modern compressor and how they achieved it. I know if I update to the 70/71 belt drive from a Mark III as well as the water pump, it should all work but I'm unsure if the FS6 compressor will line up with one of the remaining sheaves.

I may just punt and use the York compressor and have my lines modified to adapt to it.

 

Did you post about this before? I seem to remember a post about this earlier, and the york mount was fairly large? Maybe large enough where you would have enough real estate on the old bracket to drill and fabricate some sort of new mounting system for the newer compressor? I have never done this before, but just wondering what it would look like with the FS6 sitting on the york mounting bracket.

Here's a york to Sanden adapter.

Another york to sanden. I know this doesn't help much but maybe we will stumble onto something for the fs6

I keep seeing two types of FS6 compressor. One type with the mounting ears and one type with the 4 mounting feet. Which one is yours?

Here's what I am calling the "ear" type. Looks sort of like the Sanden.



Here's what I am calling the 4 mounting feet type.

 

I have not, and I tried searching the forum for this subject but I couldn't find anything and my situation may be unique between the donor motor and trying to keep factory compressor from 84.

In regards to your pictures, my FS-6 has the four feet and the one ear up top (with V-belt clutch). If I were to use the Lincoln bracket, I'd have to incorporate the idler pulley as well. From what I gather thus far, I will need a 2 sheave crank pulley and a three sheave water pump pulley. I know that the alternator, water pump and crank pulley's should line up just fine. My concern is once I convert the belt drive over to the 70/71 parts and am able to get my FS-6 compressor bolted up - will the pulley on the compressor (and also the added power steering pump) line up with the remaining pulley on the water pump. I don't expect anyone to know the answer to that for sure but maybe someone has done this before.

Alternately, I can stick with what I have which is all 69 parts, the crank driven power steering pump and the original Lincoln compressor. I will probably have to have my AC line modified and the evaporator and condenser flushed for the different oil I will need to use but that's probably easier than futzing around with pulleys from 10 different applications.

I don't know but my head hurts right now...

So retro fitting the newer compressor onto the old compressor bracket is not an option? If you used an adapter or custom made bracket to the old york bracket, you could fabricate it so the compressor would line up?

 

If I stuck with the original setup, I'm not sure if I'd be able to adapt the bracket to work with the FS6 because a majority of the attachment points are on the bottom of the compressor. The original bracket has a majority of it's attachment points at the top of the compressor. It would take some extensive modifying to make work. I'm going to sleep on this for a couple of days. I think I may just end up using the original compressor. The pisser is I just spent some good money on the factory AC brackets for the FS6.

 

Can you take a picture of your original bracket?

 

I would look for a frigidaire A-6 bracket and compressor (if you can find one) that would solve all your AC problems.
