I began this venture with a desire to rid my 1962 GT, once and for all, of vapor lock. First, I read all I could find on the internet for about a month, bought two suggested books, and exchanged several emails with a 56Jer who installed EFI on several classic cars.
The pre-reading was interesting and educational, but voluminous. After reviewing just about every EFI system on the market, new and old, I settled on HAMILTON FUEL INJECTION (HFI). A major reason for choosing Bill Hamilton's HFI was that his knowledge and customer/tech support are second to none. In reading a NG primarily for International Inc vehicles, there are several years' historical threads Many people on that NG bought from other sources, but later come to Bill for tech support they could not get from their suppliers. BIll has given advice, free of charge to those folks for years now.
My experience with HFI was that Bill was available 7 days a week by phone & email, and has the patience of Job. Though he has tried hard to make his system "idiot proof" for people like me, I had to climb a bit of a learning curve in installing mine. My next install will go much smoother, but for anyone doing a first install, tech support is critical.
As for the end product, it has exceeded all expectations. The HFI includes EST (electric spark technology); Bill took my Stude Prestolite distributor and modified it with early 1990s GM electronic ignition parts to match the computer, and even included a coil that is a dead ringer for Stude OEM.
I just took the car out tonight for a 120 mile shake down cruise, and it does EVERYTHING better than the OEM set up, including a little more MPG.
The HFI comes with everything needed except fuel lines, and vehicl speed sensor (VSS) provision, which is suggested. I bought a cruise control that includes the magnet on the driveshaft, which also provides VSS.
I simply cannot say enough good things about the HFI. Over the years I have installed many of what I call "drivability improvements" on Studes, and have driven them over 500,000 miles. Installing the HFI jst may be the best improvement to date!
