Thanks for sharing this Eric! I see that the water temp sensor is screwed into the hole where the factory temp gauge sensor goes. Did you put that sensor somewhere else or just forego the temp gauge? I’m looking into getting one of these efi systems and started planning and assumed I’d have to drill a hole in the opposite head or put a tee in the crossover tube. Looking for ideas. Thanks,
Mike

Michael the efi computer plugs into the the sensor and the handheld computer screen gives you the engine data you need such as temp, rpm,volt etc, so your dash gauge won’t work.

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.

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!

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.

Doing disc brake conversion and I need to change out the rims--what to get?

Posted by Preston Bealle on December 7, 2017 at 3:55pm 20 Comments

I'm having a mechanic change to '64 Deville convertible to disc brakes. He used the spacers that came with the kit but one side takes 2 spacers and the other 3, and there is a slight disconnect from the center hub from being so far out. It appears the best solution would not be further tinkering with spacers but a deeper 15" rim made for disc brakes. Does anyone know what rims might work that will allow the existing Cadillac hub caps to fit?  

I have read everything I can find on disc…

The Mileage reading on your speedometer

Posted by Tony and Ginny 429 on November 4, 2017 at 10:57pm 20 Comments

I hope i am not breaking anyones bubble but if you choose to remove the speedometer you can change the mileage on these cars to anything you desire it to be by just adjusting some of its internal parts and changing the numbers

That can lead to a lot of misconduct and cause you to by a car that is not correctly represented by its mileage

Just a heads up to study other aspects of the car to see if the mileage feels right for the wear and tear you may be looking at on a given… Continue
