My questions concerns the conversion of fuel injection on my '64 coupe.

What will be my hurdles to success when converting my carbureted, AC, TI car to fuel injection? I see it mentioned in some FI posts and responses but no details as why the AC causes issues. Do we have a 10 lbs. in a 5lbs basket?

Let me know. All responses welcome. I'll hang up and become a little
wiser to this conversion.

Thanks to all.

 

I have a 66 convertible with NOM small block with a Holley 750 double pumper and then replaced with a 670 vac sec Holley. I still didn't have the performance I wanted. I bought the FI Tech fuel injection setup and am very pleased with it. A lot of guys on here tried to make it work with the fuel sump in the engine compartment but had problems. I did the fuel pump in the fuel tank and never looked back. I have Vintage air but did not have any problems with the FI install.

Installing the kit was very easy and the FI set up was almost automatic. To do the fuel pump I had to pull the tank modify it and reinstall. a lot of work but it was worth it. You also can buy a FI ready fuel tank that makes it very easy. Also be sure to buy the combo fuel filter regulator about $40 so you can have a very short return line.

I have better idle, cold start, throttle response, fuel economy, as much or more HP and NO FUEL SMELL anymore.

 

Are you installing a factory FI or aftermarket. If aftermarket what one? For a factory FI there is no room with stock pulley system for everything.

 

If you are talking about a 63-65 factory FI set up it can be done and was when new. I believe the car was built for GM executive Bunky Knutsen with FI and factory A/C I am sure there are pictures of it somewhere on the Net but don't know if you will be able to see the details.
One of the reasons it was never offered to the public was that they did not want you destroying the compressors with the high revs of the FI cars. A warranty claim was not going to be a problem for one car built for a GM executive.

First question is do you have power steering? If you do and plan to keep it you will certainly have to mount the compressor under the alternator on the passenger side or the alternator under the compressor on the passenger side. The challenge is where to mount the compressor, alternator and S tube to the core support. The S tube is predetermined so if you mount the alternator on the passenger side of the engine you are going to have to look the front of the engine over to determine where you can fit and get the proper belt wrap around the compressor pulley. Another option would be to use a 1957 type air cleaner that does not use an S tube or fresh air tube from the core support. In that case you can use the same set up as a 300/350 h.p. car with A/C, and power steering.
If you want to use the factory type air cleaner with S tube it will take custom build compressor bracket and likely an additional pulley. Fortunately today we have the physically smaller an efficient Sanden compressor that will likely fit underslung on the engine. If they were able to do it with the big old A6 compressor back in the day it can certainly be done today. I have a 1966 Charger that I added A/C to it and purchased a underslung (hidden compressor mount) from these people. http://bouchillonperformance.com/inc/sdetail/577 I would contact them. They or anyone building a mount for this application will certainly have specific questions for you. I had to eliminate the factory fuel pump on mine for it to fit.

 

A/C, power steering and EFI can be done whether it is all aftermarket or modified factory units. I just finished installing a modified FI factory unit and have a factory A/C setup and Borgeson power steering. I used a Holley computer and put the fuel pump in the tank. More work than some setups, but works great. No problems with pulleys, but as you can see I don't have a full S-tube. This is installed on a 66.

 

There you go. Basically the same thing I was suggesting with a 57 FI air cleaner this semi custom air cleaner does the job too.

It looks like this engine still has the rear draft tube hole that is neatly routed into the air cleaner assembly also.
