John Addison’s Silver Bullet
From the service bay at the Sunoco and 14 Mile rolled a very tough '67 GTX built and piloted by Jimmy Addison. Bought as a 440 GTX and converted to Hemi power, Jimmy didn’t set out to build the quickest car on Woodward, he just always wanted to go a little faster.
“I had a Chevrolet and a couple different fords” said Jimmy of his early days. “I had a '62 dodge before that; then i would up with Chrysler when i went to work for Teddy Spehar.” spehars close mopar ties rubbed off on Jimmy, and before long he was combining his knowledge with that of Chrysler engineers and other racers
Jimmy didn’t set out to build a dominant street machine " I just wanted a fast car, something to fool around with, but you want to go faster and faster, you know ?"
Th GTX - named by Terry Cook, then Car Craft editor - used some novel engineering. “one of the engineers told me that the more air you get in and get out, the faster the cars going to go. One day i just dreamed up the idea of splitting the pipe just behind the collectors, and running another set of mufflers. They were '68 Cadillac mufflers because they were 2 1/2-inch in and out.”
Running a state of the art cross ram Hemi, TorqueFlite, 4.56:1 gears, and flared rear fenders with oversize Cragars and tires, the Silver Bullet ruled Woodward. Says Jimmy, "It was never beaten. We’d go out every Thursday night. Occasionally you’d get a race on a Saturday. I had a couple close calls. There was a Camaro out of Booth and Aaron’s shop. We ran several times. That was the closest. we had the GTX at several drag strips. It ran 10.30 @ 135 through the mufflers.
After Woodward’s heyday, Jimmy did some racing and then sold the car in 1975. It was more power then the young buyer could handle. it was soon parked, then drifted through several other owners.
Harold Sullivan, who as a teenager used to loiter around Addison’s sunoco station trying to get up close and personal with the silver bullet, used to get chased off by Jimmy. Harold always admired the car. having done well in business, he located it and traded a Petty Blue Superbird for it several years ago. Jeff Reif and his father, Richard, tackled the restoration, handing Jeff Dawson the interior work, and commissioning Vance Cummins for paint and body.
Today, restored to its 1968-1971 appearance, the Silver Bullet can be seen at some Detroit area shows.
