Not really, I just started heating in one spot, and once I saw some action I started swinging it around the entire outside.

On this one, I had it hanging over a little at the end, trying to...

It would be cool (pun intended) if that were hammered out, a formula, but think every OE has done many times over.

Still fun and interesting tho.

I still say it's just easier to overkill it,...

SPAL brushless fans are excellent, and are PWM friendly. They are one of the most efficient fans on the planet.

Some of the newer OE fans actually have the PWM controller built into them.

Those lower shock mount bolts I PM'd a link to you are spaced out by an inch, which helps a lot with exactly the interference you are experiencing.

I've run those Flex-a-lite 295 fan setups on 68-72 A-bodies, they work, and were my go-to. They have a rating of 4600cfm, but don't believe all fan companies use the same formula to calc CFM.

Yeah that's too close. And those are 12" fans? If so, you're only getting 'pull' thru the core the circumference of the fans. The rest of the core isn't being used.

Rebuild looks fairly straight forward, not too bad. As long as it didn't dry out and rust you should be good.

Saw a disassembly vid on youtube:

Yeah, when they list compressors as R12 or R134a, it's basically what oil they put in it for storage/shipping, the seals are compatible with both.

But if you're going to PAG and it had R12/ester...

455 studs are longer than 400s? Was not aware of that. Know there's different head bolts.

ARP lists 400-455 main studs as one, and either in 2 or 4 bolt options.

It's important to use the correct length bolts for windage tray mounting to caps. Too short won't get enough of a bite/threads, and too long can distort the caps and potentially cause bearing issues....

Studs are great insurance, use them if you can IMO.

If you're using factory caps and it's not stroked, like I mentioned, a couple washers would clear the nuts/top of studs.

If not, you 'could'...

Yes, it's with the POA valve that remains 'on'. The 'update' valve is the one that cycles. It in my understanding has nothing to do with the compressor.

If you're that close and it's all new, it makes sense to try it and see how it works.

R12 is a better refrigerant, have heard that many times. I would stick to R12 if that's an option.
