This special Advance Design pickup has come a long way from its early life on a Mid-Missouri farm. Owned and restored by Dale Jacobs of Dallas, Texas, this 1949 GMC ¾ ton has been down to the frame and came out just a little nicer than new.
It’s the old story. It looked very nice and ran just as well but a little extra touch would make it a nicer pickup. Well, the more he got into areas, the more he saw things that just were not quite right. After all it was a farm work truck for so many years. Before long you are tired of seeing so many imperfections, you check your bank account, and say “Let’s just make it a new truck”. It will only take time and money! It was taken down to the bare frame (the easiest part) and the building of the oversize model kit begins.
This four year project involved doing much research, making local new restoration contacts, and learning so much about early GMC’s.
Over the years Dale has owned several “special interest vehicles” including a 1954 Corvette. (Lucky guy!) However, he has always had a hidden desire for a pickup. Thus, this GMC became his project.
Dale’s ¾ ton has the optional 17” split rim wheels instead of the stock 15”. (These were original on the 1 ton pickup of these years). The extra 2” gives the truck a higher top end speed and lowers the engine RPM. Good during daily in-town driving.
Another very unique fixture is the intake manifold, mentioned in Dale’s article below. The original single barrel carburetor intake center hole was blocked off. Then front and rear carburetor receiver openings were installed to hold a pair of two-barrel Stromberg’s. It operates excellent and is probably the only one of its kind in the world! What an eye catcher! He says it easily cruises at almost 70 mph!
The following is a few of the special features Dale wrote about on his GMC. No doubt it is an overview and is the “tip of the iceberg” of all he has done to make it such an attractive well-appointed truck.
Dale’s Personal Story:
A 4 year “frame off” TOTAL restoration of this “numbers matching” GMC 3/4 ton pickup.
The “Ron Kelly Designs” complete rebuild of this original drivetrain and chassis included the GMC 228 engine long block (.08 over rebore), head, flywheel, clutch, 4-speed on the floor transmission with “granny” gear, drive shaft and rear end, all dynamically balanced. Modifications to improve performance include full-flow oil filtering, dual 2-barrel Stromberg carburetors adaptation to original intake manifold with new linkage, and Fenton dual exhaust headers with custom muffler routing.
The chassis rebuild involved frame powder coating, front and rear spring leafs with helpers, Delco lever arm shocks, duel master cylinder brake system, front end and steering linkage with drive box.
The electrical system conversion to 12 volts included the original Delco starter and generator, regulator, new Mallory dual point distributor and coil, new wiring harness, 4 corner lighting with halogen headlights and turn signaling. A new water pump, radiator with expansion cylinder and hoses improve the cooling system.
All body panels were COMPLETELY disassembled and, along with the cab, subjected to a strip and de-rust total immersion process. Reassembly with new fasteners was preceded by extensive applications of epoxy and urethane primers and initial custom lacquer paint then followed by final lacquer paint and clear coatings.
Cab restoration involved new door handles, hinges and panels, headliner with insulation, sun visors, gauge cluster and speedometer, vintage GMC reproduction stereo AM/FM radio and 7 new glass windows allowing a surround view. The air flow heater with control valve and defroster ducts, vacuum wiper motor with linkage, fuel tank with new sender, and all pedal controls were also restored to original specifications. Traversing seat with era appropriate new upholstery allows comfort with a vintage signature. Firewall, roof, floor and doors all received sound deadening applications.
Finishing touches include the re-chromed original grill, badging, radiator fan and added dual trumpet horns. Color coordinated powder coated engine side and valve covers enhance the engine bay. Also evident are new bumpers with valences, vintage Unity spot and fog lights, chromed fuel tank linkage, and powder coated original split rim wheels with new 750-17 tires. An eye-catching top grade oak bed and side rails with stainless linings and fasteners complete this classic restoration.
