A combo similar to this was tested in the Golden Commando's Goldfish. It ran a best of 12.89 @ 107. Even though the Dart GT and the Barracuda weigh about the same, the Barracuda has a 175 pound weight advantage over the rear wheels. Ted Spehar said the D/Dart engine/program would have been better in the Cuda. But they wanted/needed a Dodge race car.

From Mopar Muscle Jan. 2014

Many of the cars featured in this section of Mopar Muscle have a history, but most didn’t build that history at the racetrack. In fact, the vast majority of classic Mopars rarely saw any track time at all, as most of these cars were simply daily drivers or cruisers. This month’s Hidden Treasure is different, however, as it’s a ’66 Dodge Dart, which was first owned and tuned by Mopar’s “Mad Scientist” Ted Spehar, and driven by Ralph Costa.
Ted Spehar was somewhat famous around Detroit during the ’60s and into the ’70s, known as a meticulous engine builder with ties to factory-backed Mopar race teams. Ted also tuned cars for the Chrysler Corporation, including the now famous ’69½ Road Runner that Ronnie Sox took to a mid-12 second elapsed time during a Super Stock Magazine track test. Another project sent to Spehar by Chrysler is the car featured here, which was one of the approximately 50 D-Darts used for drag racing development. This car was featured in the May ’67 issue of Super Stock Magazine, and the article highlights the numerous modifications to both the car and the engine, which resulted in elapsed times deep in the 12-second range.

The D-Dart was originally co-owned by Ted Spehar and Ralph Costa, but at the end of the 1967 race season, Ralph let the car go to Ted, along with the payments. Ted then sold the car to its second owner, Jon Rasbach, who also raced it before eventually selling the car to Chrysler engineer Al Adam. After that sale, the car was modified slightly, but basically preserved in as-raced condition, and kept in Adam’s mother’s garage for more than 30 years.

Ted Spehar
THE "SILVER BULLET"

The Meanest, Baddest Street Racer to Ever Hit the Pavement!

On the surface, the "Silver Bullet" was pretty much what it appeared to be -- a much-modified Plymouth Belvedere GTX hardtop that was owned and driven by Jimmy Addison, a quiet, matter-of-fact mechanic who worked at Ted Spehar's Sunoco gas station on Woodward Avenue in Birmingham, Michigan. Being good with a wrench, it was perfectly reasonable to assume that Addison simply had a way with Chrysler products, knowing exactly what to replace or revamp in order to turn a "Mopar" into an all conquering street performer. The fact that he had access to all sorts of exotic racing parts was also plausible because his boss, Ted Spehar, was in the business of building racing engines at his station. Presumably, he sold parts to Addison at wholesale.
But Addison, Spehar and the "Silver Bullet" were much more than that. In truth, they were agents of a high-performance hardware and technology think-tank in Chrysler Corporation's factory racing department in Highland Park, Michigan. The 1967 Belvedere GTX in question was actually a rolling test bed for parts and ideas that originated among an elite group of engineers who had plotted Chrysler's considerable racing success in the 1960s. This innovative group, headed by veteran Bob Cahill, and staffed by the likes of Tom Hoover (who created the 426 Hemi) and Dick Maxwell (a member of the legendary Ramchargers racing team), concluded that winning on the racetrack wasn't enough all by itself to win the respect of young buyers. What the situation called for were stock-looking cars, in the hands of seemingly everyday customers, that were faster on the streeet than anyone else's.
Of course, other carmakers such as Pontiac, Chevrolet and Ford reached the same conclusion. The result was a profusion of factory-backed, street-legal GTOs, Mustangs and Chevelles that on any given evening could be found cruising the Detroit suburbs, looking for action. Chrysler's idea was to counter with a street machine so powerful, so fast, that nothing out there could touch it. The first step was to requisition a well-worn Plymouth Belvedere GTX that had been an engineering test car and sell it to Addison for a dollar.
The "Silver Bullet" then, was a marketing tool as well as an engineering test mule. In Addison's hands, with Chrysler's guidance, it took on a number of lightweight components, such as doors, hood, window glass, front crossmember and bucket seats, that pared 500 pounds off its production weight. The monster 487-cubic-inch Hemi V-8 under the super stock hood scoop was equipped with a 4.25" stroker crankshaft, oversize TRW pistons, Racer Brown camshaft, 10-quart oil pan and aluminum cylinder heads. Fuel was delivered to the twin Holley four-barrel carburetors via a Stewart Warner electric fuel pump, while Hooker headers directed exhaust to the four '68 Cadillac mufflers through 3" pipes. Transfer of power to the M&H drag slicks at the rear was achieved with a modified Torqueflite automatic transmission, while compliant front shock absorbers teamed with super stock rear springs to achieve the desired rearward weight transfer. The "Bullet" in full street trim could cover the quarter mile in 10.50 seconds at a speed of 132 mph. Not bad for a docile-looking Plymouth hardtop!
Today, the "Silver Bullet" is the proud possession of Mr. Harold Sullivan, a Mopar musclecar collector who tracked the car down and restored it from a state of considerable deterioration to its present pristine state. Harold found another GTX and built the "Silver Bullet II". He still races both cars!

Bill wrote this story in May of 2006, but it wasn’t until 2007 when I first saw the Silver 1967 (not 68) Plymouth GTX known as the Silver Bullet. The undisputed “King of Woodward Ave” drew a crowd for days at the legengary Woodward Avenue cruise and stirred up quite a controversy when there were two of them! (that’s another story about the Silver Bullet)
Please enjoy this story from a man who was there and knew the owner of the Silver Bullet, From:

Jimmy Addison.
The Passing of a Legend


Now, from the mid-‘50s through the mid-‘60s, the north Woodward suburbs were hotbeds for young rodders with something being built or hopped-up in at least one garage on every block, and, with no shortage of young talented mechanics in Birmingham, Jimmy found himself right in the midst of it all.

One such ‘talented mechanic’ back then was Ted Spehar. Barely old enough to drive, Ted and friend De Nichols rented a garage to work on their cars. The garage was just across Woodward from Jimmy’s house, so it wasn’t long before the like-minded young rodders hooked up and began a lifelong friendship that took them through many ventures and adventures that ultimately led them to unimagined heights in the realm

Jimmy first went to work for Ted Spehar in 1965. Ted owned an old Texaco station on Maple a couple blocks west of Adams in Birmingham. Besides accumulating a brisk neighborhood business, Ted had become acquainted with Dick Branstner. I used to see the ’64 Color Me Gone Dodge sitting out in front of the station, along with a little red Dodge pickup with a full-race Hemi protruding through the bed just behind the cab. My first glance at the yet unlettered, carbureted Little Red Wagon, then driven by Jay Howell. It was at this time that Jimmy and Ted began their long affiliation with the Chrysler race program.

In late 1967, Spehar bought a Gulf station on 14 Mile Road just east of Woodward in Birmingham and (I believe) it was at this time, or shortly thereafter, that Jimmy assumed ownership of the now-famous Sunoco station.

In the late ‘60s the Sunoco had become a nightly hangout for what was to become Chrysler’s “Direct Connection” gang. An assortment of Chrysler engineers that included Dick Maxwell and Tom Hoover, the man affectionately known as the “Father of the Hemi.” They were there to test speed parts on the street, plain and simple.

Well, one of the cars that were used as rolling test labs was a blue 440-4-barrel powered ’67 Plymouth GTX that was used for drag testing. The car had never been titled. It was snatched right off the back lot, used and abused, and eventually given to Jimmy Addison. The 440 came out, in went a lightened Hemi K-member, followed by a heavily massaged 1968 426 Hemi, the manual-shift tranny, and a Dana 60 rear end with a set of 4.56’s and a pinion snubber for traction.

Woodard Avenue plus Ted Spehar plus Chrysler Engineering must have been interesting times.
Not good for the career for the engineers to be directly involved in street racing, but through Spehar/ Addison, a few parts got some street time/ testing.

Spehar and Costa's old car. Rasbach and Flynn's old car. Al Adam's old car. Wait..................it's my car.

I got a pair of M/T ET Drags -- 28.0/9.0-15's that are mounted on 15x6 rims. The rims have 0.0 offset. Put them on back in April just to see how they fit. The passenger side tire was rubbing on the Super/Stock leaf spring clamp. Put a 0.192" spacer in and now it just clears. The driver side fits great.
