I'm thinking about replacing my A6 compressor with one of these. My A/C cools fine but the A6 has a tendency to sling oil from the shaft seal which makes a mess. Is this Pro6ten compressor really as "drop in" as they say? Same mounting, hoses, etc?

Kurt I bought the compressor from OPGI, it works very good.

Hi Eric, what kind of A/C compressor is that?

Paul I have the Holley EFI on my Pontiac,  it’s not the sniper  it’s the full system and I like the FI TECH better

Hi Eric I’m restoring a 63 Fleetwood Sixty Special in New Zealand running a rebuilt 390

My mechanic said I should look at fitting the Holley Sniper EFI system but your one looks good and by the reviews seems to perform well too and cheaper than the Holley.Is that the standard Cadillac manifold and can you give me tips on what linkages I need and what’s the canister model?

appreciate the advice not many 63 Caddy experts in New Zealand!

cheers Paul

I don't think it's the best idea to drill into a head and tap it. If you look in my thread about emissions you can see the inline rad hose adapter I use for the thermally ativates vacuum switch. It came with a 1/4" hole but I drilled and tapped it for 3/8" pipe. Just a few buck on Amazon.

Thanks Eric.  I want my factory gauge to work so I'll have to find another place for that sensor.

Clovis, I asked the question because I had been looking around my engine for a spare plugged off factory hole and wondered if Eric found one.  Looks like Cadillac only gave us one tapped coolant passage and used it for the dash gauge.  After I convert and the car is tuned, I'll be unplugging the handheld computer and using the factory gauge, so I'll need to make another hole.  I'll probably either tee off the hose fitting on the back of the crossover tube or drill and tap a new hole on the opposite cylinder head.

Anyway, yeah, this isn't my first.  I do all my own work except bodywork and upholstery.  I've converted several cars to EFI but this is my first Cadillac.  I'll have mine completely apart as well for a complete under-hood restoration.  No worries, just planning my attack!  LOL.

I'll check out your posts, thanks!

Micheal are you a hands on guy when it comes to your car? Have you ever done major work such as this? I ask these questions because this is not a simple installation. Tuning it is also not so simple either. If you've done this before jump right in with both feet as it's very rewarding.
Your questions about the temperature sending unit tells me this may be a bigger project, automotive wise, than you've ever tackled before. I highly suggest you find a reputable shop that has done at least two of these installs before. I eat sleep and live for this kind of stuff all my life so I didn't even bat an eye when it came time to do it. Since everything was apart I also detailed the engine compartment and totally went through the comfort control system. I also rewired and added electric fans. This was done simultaneously with the efi install.
If you are thinking about doing it still read my posts, there are several, on the efi and comfort control installs. Happy building sir.

63 guidematic issues

Posted by maurice lapoiinte on November 24, 2019 at 3:10pm 0 Comments

 So my 63 guide matic headlamps stay on low beam all the time. I have so far bypassed the system and everything works normal. I have been thru the trouble shooting in the manual but this is where the confusion begins.on my car when the power relay is powered I have low beam and when its not powered I have highbeam, this appears to be opposite what the diagnosis says should be correct.The wiring is all original and no wires have been mixed up.has anyone ever unplugged the 2 wire connector…

Another advantage of the Pertronix III

Posted by Doug Scarrow on November 23, 2019 at 11:12am 1 Comment

   Having tried both the II and III I can say the multispark feature of the III offers a smoother idle . It is also easier to install .Does not require removal of the distributor

Stuck at two red (dash) lights!

I hope someone can help solve these two electrical problems that appeared one after the other.

By way of background: The car, a '64 Eldorado has very limited use. It was at a restoration shop for 15 months until last January-  that supposedly did a bunch of wiring repairs including rebuilding the gas gauge that still hasn't worked properly, and the clock that hasn't worked, and re-soldering the broken wires in the drive door. All window and seat controls appear to be…
