  • Fuel System: 1963 Studebaker GT Hawk Carburetor

    Hi Guys
    I need some help with a carb replacement for my 1963 GT Hawk, 298 , automatic, A/C, PS car. (Not a supercharged car). I recently bought this Studebaker which was in a garage for nearly 30 years. The neighbors didn't know it existed as they had never seen it. Good buy for me as I was there when the family decided to sell..
    It has 40,000 miles on it. The previous owner was a member of the family who bought it new. Once purchased and brought home, it started with a jump. Brakes are soft but I have receipts that they were rebuilt in 1990 AND the car has the same miles as the receipt!!! Hard to believe that the car was repainted, reupholstered and put in the garage and covered. I bought it. Motor # JT 1792. Door stamp 63V 29474.
    The carb is leaking gas. I need some counsel on the replacement. The research I have done says Edelbrock 1403 500 cfm. as the replacement.
    Do you agree or do you have a different recommendation??
    Many thanks.

    Wow! Champagne Gold, power steering, power disk brakes. That's quite a car and a great find.

    Welcome to the forum.

    Since you are new to Studebakers, please do not fall into the trap of thinking they are poorly designed cars. They are actually very well designed and really do not need to be modified with systems from other brands. If you bring the existing systems up to snuff, replace bushing, bearings and such, you will have a well running, well driving car.

    I only say this because there is a feeling among people who do not know Studebakers, that the way to fix them is to jury-rig other parts onto them, particularly when it comes to the front suspension.

    I agree about the new carburetor that folks are mentioning, however. I have one on my 60 and it runs beautifully.

    Most of the problems come from neglect or from previous owners who had more enthusiasm than ability.

    Enjoy your Hawk. It's a pretty cool car. How about some more pictures?

      Welcome to the forum, there is a wealth of knowledge here and all you have to do is ask for help/advice. It looks like you make an excellent find and more pic's are always encouraged. I noticed the chrome pieces on the engine and I wonder if this is an Avanti engined car? Might you have the production order? If not you can obtain one from the Studebaker National Museum in South Bend. Good luck and happy motoring, Bill.

        Very nice car. 29 years sitting and you may want to go through the consumables. Why not just have your carb gone through? I sent mine out to a rebuilder in Los Angeles and they did a fine job. Good luck!

          Your first photo shows the engine with a chrome air cleaner & valve covers. Although Studebaker offered an engine "dress up kit" it may also indicate the optional Avanti R-1 engine. That can be determined in the STAMPED number on the left front of the engine (to the right looking at the engine from the front of the car). If the engine number starts with the letters JT you have the Avanti engine, however, if it starts with the letter P, that indicates the standard 289 engine. Some members here have the list of serial numbers for the JT equipped cars, so if you like post the serial number from the drivers side door hinge post. Greetings & welcome to the forum!

              Would the "dress up kit" have included the re-circulating gas line back to the tank, as indicate at the fuel filter? Looks like a factory R1. What a ride, PS, PB, A/C, 4 speed.

                It's a Powershift car, since it has the floor shifter, and it has the "Avanti Powered" badge on the fender. It's either an original Super Hawk, or a clone. Very nice find!

                  With the additional pic's, I believe Gord hit the nail on the head. It appears to be an R1, powershift, p/s, p/discb, car, which could possibly be a SuperHawk if it has the additional "package" items. Howard if you could find the engine # as suggested previously and the serial # and post them here, maybe one of the guy's that have all the "super" car info could look it up and post the results for you. As stated before the engine # is stamped on the top left corner of the block itself, near the left head. The cars serial # is on a spot welded tag on the drivers door forward post (open the door and look on the forward hinge post). Keep us informed as you have created some excitement for all of us.

                      Let me work on the numbers and get back to you on the 1403.

                        Thank you Colgate Studebaker!!!!
                        I checked the motor this afternoon. I posted the proof.
                        Its a JT 1792 motor.
                        So....help me out...I'm a beginner with
                        GT Hawks. How many 1963 Super Hawks? Whats in the number?
                        I'm having a ball....thanks to this site and some great information!
                        Best regards

                          Just to clarify things a little....A Hawk or Lark factory-equipped with an Avanti engine isn't necessarily a "Super Hawk." The term Super Hawk means one with ALL the Super Hawk high performance equipment. Studebaker sold the Avanti high performance equipment ala carte, or one could order ALL the high performance equipment and that car was called a Super Hawk. I have two '64 Hawks, both with Avanti R1 engines, and neither is a Super Hawk.

                            As I said above, get the production order from the Museum and that will tell you whether it is a SuperHawk or not. There are a few guys that have the research info on all the Avanti equipped cars, but we'd need one of them to chime in here. Howard, I'd wait on replacing that carb until you find out the true identity of the car. If it is truly a SuperHawk then my suggestion would be to have the original carb professionally rebuilt and use it that way. If you want to sell the car it will have more value with the original equipment vs. replacement. Just my opinion, Bill.

                              Thanks Dwight....I have one article specifying the package details. Sway bar in the rear....shocks...disc brakes front....some other things.
                              More checking by me is required, I believe. I think that about 4000 total GT Hawks were built in 1963. I did not see how many were Supercharged, how many super Hawks and how many were standard 289, 2 bbl. In any case...I may take the counsel offered here to rebuild the factory 4bbl carb as that may be important to a buyer.
                              Thank you for the input....feel free to give more as this is my first Studebaker.
