In 1966, only 984 Bonnevilles were equipped with the code-YJ Tri-Power 421 engine and a Turbo 400 automatic transmission. Featuring factory ratings of 356 hp at 3,800 rpm and 459 lb-ft of torque at only 3,200 rpm, this full-size luxury musclecar pulled hard from the factory. As part of the driveline restoration, the Tri-Powered beast was pulled and rebuilt to quench its thirst for oil.
After knocking off the red clay and prepping the surfaces, the frame and floorpans were painted in the same Centari enamel. The suspension features the optional ride-and-handling package that had higher-rate springs and shocks for a firmer ride. Replacement ACDelco shocks for the front and rear were painted to match the factory appearance. N.O.S. and Moog components restore the front suspension, and a factory .75-inch front stabilizer bar supports cornering duties. Out back, the upper and lower control-arm bushings were replaced with factory pieces.
In order to absorb the pulses of the pavement and maintain the original ride characteristics, the Bonne rolls on Atlas Cushioner bias-ply tires measuring 8.55x14 inches. The original 14x6-inch aluminum 8-Lug wheels were owner restored. Their integral 11-inch drums were relined, new shoes were mounted, and power assist makes pedal pressure light.
ConclusionOne look at the Starlight Black convertible was all it took to send the owner into a 10-year journey toward perfection. Aptitude and attitude define the full-size offerings from Pontiac, and only the diehard enthusiast embarks upon a restoration that yields far less financial returns than the rare A- and F-bodies.
What is realized is much more substantial and long lasting; the uniqueness of a classic full-size Pontiac and the styling to turn heads. "I drive my Bonneville 1,500-2,000 miles a year," said Ken. "I enjoy summer cruises and the top-down experience of a full-size luxury musclecar. The body is clean-cut and contains smooth, timeless lines."
The driver is surrounded by a panorama of real walnut veneer, while the raucous 421 engine is monitored courtesy of the optional gauge cluster that features oil pressure and engine temperature gauges in the center instrument panel, and gasoline and amp gauges, and a clock angled toward the driver over the optional AM/FM radio with reverb.
From a $500 tattered mess to one of the most striking cars of any era, the craftsmanship, pride, and effort to transform and refine this behemoth to the lofty levels it has now achieved on the national scale is phenomenal.
The next time you take a break from the rigors of daily living and ask cousin Joe to go for a ride, remember to slip a couple grand into your hip pocket, clear your calendar for the next 10 years, and keep a keen eye out for the timeless lines of a full-size Pontiac.
