    FI Unit Serial Numbers

    The serial number on my 1962 is 2XXX which is too high for a January car. With only 1918 Fuel cars produced that year, how/why did they buy so many FI units. Over 800 units in the "over the counter" seems excessive.

    The first unit was 1001, so a 14,000 serial no car should have around no. 3000. I would expect a mid-January car to have around no. 1800.

      Re: FI Unit Serial Numbers

      Patrick, Where did you get the info on the 800 service units? First of the 62 service units were sold as service replacement for 57 to 62. In the late 60's they sold for $495.00 each. You had to order the base plate separately.
      Around 1975 Jon Blanchette had a list of the various models from 57 to 65. But his list is not accurate as far as SR units go.
      The 62 FI unit as we know it came with three different unit numbers. Typical St. Louis cars came with 7017360. Service replacement units could have also had a tag that read 7017370 and also 7017365.
      Jon said there were 16 service 7017360 units, 22 of the 7017365 & 47 of 7017370.
      So add up 16+22+47 = 85 units.
      Oops. IT just hit me where you got the 800 at. Sorry.
      Meanwhile Jon Blanchette says 2131 62 FI cars. The 1918 figure must be the latest from NCRS?
      One thing that puts a wrench into all of the above is not in print anyway as it's just hearsay.
      Frank Scibica of RP in the old days was my close friend. Frank told me never to believe any of the numbers you hear on service replacement units made and sold as the numbers were fiction. He said record keeping was poor and the bean counters were on the RP brass to shape up and sell the huge inventory that was left behind after every model year. You figure out the rest.
      A lot of the old timers here knew Frank quite well.

      I bet that Rev Mike has Dales list. If not Ken Hansen of Orin Dales has it. John

        Re: FI Unit Serial Numbers

        What I was trying to get was the relationship between car serial numbers and the serial number on the FI unit based on known original FI cars. Those that may have some data, seem to keep it close to the vest.

          If you read between the lines on my last post, that's what you got.

            My 1962 Corvette Serial # 106331, born on Feb. 2 has its original engine and fuel injection. My FI unit # is 2127. So, is your car built in late January? Why not tell us the exact numbers of your car. Sounds like your car may be within a normal range.

            Mike's estimate at 1800 looks pretty good, . . .for mid December? Looks like FI sales were running ahead of what would be a mathematical average, or maybe first in was not first out. I guess I should list my engine code since the FI units would have been installed at Flint. Here it is: F0126RF.

            You guys who make lists may save my information. Well, it is already public.

                  That is curious. Your engine was built more than a month before mine, but your fuel unit has a serial number that is 171 units after mine. I also looked at the birthday calculator on C1 Registry and got Jan 11, 1962. Did you get the Delivery info from NCRS to confirm this? I also see that your car is listed there and is under restoration, so I assume it has never been restored before? What is the history of the car? Honduras maroon with a beige interior; I like that! You have a greater time between engine assembly and final assembly than mine, but that can be explained by poor rotation of engines at St. Louis, not first in, first out. The FI unit numbers are the mystery. It would be nice to see information on other cars around this time.

                    Re: FI Unit Serial Numbers

                    #5736 has FI unit 1968
                    #4187 has #1712
                    #5087 has #1823
                    That is info I gathered prior to 1981, and the cars were unaltered originals. Cars like that are almost impossible to find today.
                    Based on this and additional data I have collected, I believe that your FI unit has been changed at some time in the past. The unit on your car is too late for your car. A unit that is way out of sequence but is earlier than the car is possible; a unit way out of sequence but too late for the car isn't plausible.
                    There's a date on the bottom of the baseplate of the FI unit, but that's a very easy piece to change out as well. However, a baseplate can be dated right and a serial tag too late because it's easy to change out a unit without removing the base plate.

                      Re: FI Unit Serial Numbers

                      My car was originally from Birmingham, AL. I could not get delivery data from NCRS because they said the microfich was damaged. It was a drag racer between 1968 and 1974 when it was disassembled for restoration. I doubt the engine is original. I have owner history back to 1968. The 64XXX milage is original based on titles from NC and VA (where I bought it). The colors are correct as indicated on the cabin rear wall crayon. It is a real FI car based on all of the indicators I know (strongest being the dimple on the firewall by the tach cable hole). Everything works, including the washer/wiper system.
                      She may not be all original but she is now as correct as I can make it.

                        Thank you for the information, Mike. For the record, the casting date under my baseplate is 11-25-61 (unit 2127). The triangular foil tag has 7017360 and below that are C A2 04 04 . What are the significance of these codes? Oops just answered my own question by looking at the Judging Guide. Looks like date code A2 fits.

                          Patrick,
                          Does your FI unit have a triangular metal tag on it? Would be interesting to know the date code. I would agree with Mike based on the evidence about your unit being a later replacement.

                          Why do you doubt the engine is original. Has it been restamped? What is the casting number and casting date? Can you post a photo of the F1219RF and convin stamps?

                            HI Bruce, Nice that you have the triangle foil tag but just so you know the tag is a tad late for your Jan 11th or so car.
                            The tag should predate your engine by a month or so. John

                              I think you are getting the two cars mixed up. My car (5234) is Jan 11, Bruce's (6331) is February 2nd.
