1969 Barracuda Formula S - All In The Family

Under the hood rests the numbers-matching 340 small-block built by Bryan, owner of Sloan Racing in Rancho Cucamonga, California. The bores were increased to 4.07 inches, and a Dragon Slayer crankshaft increased the stroke to 3.79 inches-together this generates 394 ci of Mopar power. Combined with an assortment of other well-matched internal parts and a free-flowing exhaust, it has powered Doug into consistent 10-second passes on motor, with a best of 10.62 at 124 mph. Just as impressive as the elapsed times, the Barracuda maintains a high level of streetability. Throw a quiet exhaust on it, and it would be a comfortable street car.

The interior was restored by Doug's family. Only a handful of pieces were sent out to be worked on by specialists, but for the most part, the interior was in good shape. Legendary Auto Interiors provided the necessary interior pieces, including seat covers and carpeting, which were purchased through YearOne.

When everything came together, Doug finally had the car he wanted-something that could win at car shows, yet still put big-block Chevys and Fords on the trailer. He has several trophies to back up his accomplishments, proving the abilities of his well-balanced Barracuda.

The project took about three years, but the A-Body has been in the Sloan family since the car was brand-new. Doug, with the help of his parents and brother, has made this family affair into one incredible Mopar.

Mopar Power
Engine: Built by his brother, Bryan Sloan, the original 340 block has been punched out to a 4.07-inch bore and is fitted with a 3.79-inch stroke that's 394 ci. Inside, you'll find 11.0:1 compression CP pistons, Eagle 6.250-inch connecting rods, and a forged stroker Callies Dragon Slayer crankshaft. The valvetrain consists of a .586-inch lift, 260-degree duration solid flat-tappet camshaft from Comp. The 2.05-inch intake valves and 1.80-inch exhaust valves use Comp Beehive valvesprings and Pro Magnum rocker arms. The engine also features aluminum Edelbrock cylinder heads ported by IMM in Indio, California. The exhaust system begins with a pair of tti 15/8-inch headers with 3-inch collectors and finishes with 3-inch Borla XR1 mufflers.

Fuel, Air, Spark: On the intake side, Edlebrock was used again for their Super Victor aluminum intake and a custom PC built Holley HP 750 carburetor. An MSD electronic digital 6 ignition system and distributor carries the spark.

Transmission: The four-speed was replaced with a ProTrans automatic with a 10-inch Turbo Action 3,500 stall torque converter. It uses a Precision Performance Products shifter and a ProTrans shift kit.

Rearend: The rearend received upgraded Dutchman axles, a Detroit Locker differential, and Richmond 4.30 gears.

Sure Grip
Suspension: A '73 large bolt-pattern front end with tubular upper-control arms by Firm Feel holds the front end up and uses QA1 adjustable drag shocks. The rear uses Rancho RS9000 and CalTrac Bars with mono leaf springs.

Rims & rubber: Weld Rod Lites are worn front and rear. The skinny 15x3.5 wheels in front use 26x7.5-15 Mickey Thompson tires; the 15x8 rears have 275/60/15 Mickey Thompson ET Street Radials.

High Impact
Paint & Body: Strip Clean acid dipped the body to remove the factory paint. After they were done, Danny's Auto Body covered the Barracuda with black PPG 2 stage paint. A fiberglass hood, hoodscoop, and front bumper were purchased from AAR Quality Fiberglass and reduce the weight of the A-Body.

Interior: The seats were recovered, and the carpet is new from Legendary Auto. Doug's parents completed the upholstery while he pulled apart the instrument cluster and stripped the dash with his brother. The interior panels, dash, and trim are all original, and CV Vacuum did the rechrome work. The back seats, radio, and speakers were taken out since they weren't necessary. Doug wanted a clean, basic interior and removed the console to make room for the shifter.
