Summit Now Offering Herb Stuart ’69 Shelby GT500 Mustang Part Combos

New from Summit – they are now offering Herb Stuart 1969 Shelby GT500 Mustang Parts. These part combos showcase many of the parts used during Herb’s three-year build Pro Touring build. See more details below.

Official Release:

Here’s a story for you. Herb Stuart’s father worked for the A.O. Smith Company as a safety engineer. The company made the fiberglass pieces for the 1968-70 Shelby GT350 and GT500 Mustangs and also built the cars for Ford. In 1970, Mr. Stuart found out a 1969 GT500 demonstrator was sale, so he quickly bought it. The car was his daily driver for many years—he even threw snow tires on the back and drove it during Wisconsin’s brutal winters.

Herb inherited the GT500 in 1983 and put it in storage, where it sat for over 30 years. In 2016, he pulled the car out of hibernation and transformed it into a Pro Touring style car for street and autocross use. Shelby purists may get the vapors, but we’re sure Dad would approve.

Summit Racing’s Herb Stuart 1969 Shelby GT-500 Mustang Parts Combos showcase many of the parts used during the three-year build. You may not have a Shelby, but all of these upgrades will fit any 1969 Mustang with a 428.

Short Block Combo
The Shelby’s 428 cubic inch FE big block got bumped to 462 cubic inches with an Eagle Specialty rotating assembly with forged Mahle pistons. The cam is a custom COMP Cams hydraulic roller rated at 228°/234° duration @.050″ and .634/.627 inches of valve lift. Other components include Canton Racing and Melling oiling system parts, an ATI Super Damper, and an ARP main stud kit.

Top End Combo
Herb replaced the factory iron cylinder heads with Edelbrock Performer RPM cylinder heads, upgraded with Harland Sharp 1.76 ratio roller rockers and COMP Cams valve springs better matched to the hot roller camshaft. The Shelby is currently running an Edelbrock Pro-Flo 2 EFI system, which is no longer made. Our combo includes a much-improved Edelbrock Pro-Flo 4 system. Ignition is handled by the Pro-Flo system’s distributor, a Taylor coil, and AFIS Power ignition wires.

Exhaust and Cooling Combo
The Shelby’s exhaust system features Hooker Super Competition headers with 1 3/4 inch primaries. They dump into a custom 2.5 inch dual exhaust system fitted with Pypes M-80 mufflers. The 428 is kept cool by a Griffin Exact Fit radiator with dual 11 inch electric fans. The combo also includes DEI Titanium exhaust wrap, a Summit Racing stainless steel radiator overflow tank, and Continental radiator hose.

Driveline Combo
An American Powertrain Tremec TKO 600 five-speed transmission with a Quick Time bellhousing replaces the original C-6 automatic. American Powertrain also supplied a flywheel, hydraulic release bearing kit, and White Lightning shifter. Our combo also includes a RAM Street dual disc clutch. The Shelby’s rusty 9 inch rear axle was replaced with a custom-built 9 inch with an Eaton Detroit Trutrac differential and Richmond Gear 3.50 ratio gears.

Suspension and Brakes Combo
The Shelby’s front suspension was replaced with an AJE Suspension tubular K-member fitted with tubular A-arms and power rack-and-pinion steering. Out back is an AJE four-link rear suspension conversion with coilovers. The brakes are Wilwood Superlite discs front and rear, and the Mustang rides on 18 inch American Racing Torque Thrust M wheels shod with Nitto NT01 rubber.

Sheetmetal Combo
All those years of winter and road salt did a number on the GT-500’s body. Herb did a rotisserie restoration, replacing bad metal with Scott Drake reproduction pieces including front frame rails, rear quarter panels and wheelhouses, door shells, and radiator shell. A Global West export brace helps stiffen the front end of the car.

Interior Combo
A pair of TMI Pro Series seats and Crowe Enterprizes five-point race harnesses keep driver and passenger secure through the twisty bits. AutoMeter Z-Series and Sport-Comp gauges keep an eye on the engine, and Herb guides the Shelby around the autocross course with a Scott Drake Corso Feroce steering wheel.

Completer Combo
This combo features an Aeromotive Stealth 340 fuel tank and pump kit, Painless Performance wiring harness, a Billet Specialties Tru-Trac serpentine belt drive, a Vintage Air Gen-IV Sure Fit climate control system, and a Scott Drake front windshield. It has other very important stuff like an ARP engine bolt kit, an E-Stopp electric emergency brake, and Dynamat sound insulation.
