1967 Dodge Coronet - Build Or Buy

Picking Up Where The Last Guy Left Off May Have Its Advantages.

There seems to be some sort of unwritten rule governing the realm of drag-dedicated cars, the gist of which states that to truly gain the respect of your motorhead peers, you must create your machine with your own hands. Buying a finished car or writing a check to have someone else spin the wrenches is verboten, and it won't get you a seat at the cool-kids' table the next time you go to the track.

Glenn Forbush's yellow Dodge doesn't represent an attempt to buy into the gearhead fraternity even though he bought it much as you see here. He became a member back in 1978 when he purchased a '70 Challenger, then ditched the 318 for a 440. Twelve years later, he picked up a '74 Challenger Rallye-another 318 car that had received a 440. It was to be a mild refresh and repaint, but it turned into a total teardown, right there in the Forbush garage. Three years passed before the Challenger re-emerged with show-car finish and trim and a better 440, mostly as a result of Glenn's own effort along with help from his then-adolescent daughter and some friends.

In the meantime, Glenn had purchased a '67 Coronet so he would have a vintage Mopar to satisfy his jones while cruising the local scene. It was supposed to be sold upon completion of the Challenger, but once the E-car was done, the Forbushes missed their garage sessions. That set a plan in motion to turn the Coronet into a mild street/strip machine. "I started doing the math to figure out what it would cost, then I saw the yellow car on eBay." The Coronet up for bid was a fairly radical street machine, with a 500-inch big-block slung from a motor plate, a manually shifted TorqueFlite, a four-link rear between the enlarged tubs, and a 'cage. "The car was a lot more serious than I had intended for the project we were planning, but the Buy It Now price was a lot less than the estimates I was coming up with." After lengthy conversations with the owner, a deal was made and the big, yellow '67 came back to So Cal. "The car turned out to be just what the previous owner had said, and I'm pretty sure I paid about half what he'd spent to build it."

If there were any disappointments, it was only after the first trip to the strip, where the best the Dodge could muster was a 12.19 at 110 mph-not great considering its hardware. But after subsequent ignition and carb tuning, Glenn had it down to 11.61 at 114, though his sights are set firmly on the 10s. "My next move will be a custom converter; this one seems to be slipping too much in High gear. Next I'll go with a custom grind on a solid-roller cam, and I'm thinking of shaving the heads to get compression up to 10.6:1." By that time-and it won't be long-Glenn should have enough of the Dodge's grease under his fingernails to squelch any doubt that he's earned the right to take credit for its performance.

Tech NotesWhat: '67 Dodge CoronetOwner: Glenn ForbushHometown: Riverside, California, former home of the world-famous road course.

Engine: An MP crate engine displaces 500 inches thanks to an MP siamese-bore block bored to 4.38 inches and a forged 4.15-inch stroker crank. Flat-top pistons make 9.8:1 compression and swing from H-beam rods.

Heads: Aluminum Edelbrock Performer RPM assemblies with 2.19/1.88-inch valves have been CNC-ported by Modern Cylinder Head in Clinton Township, Michigan, so that the intake side now moves 325 cfm; exhaust is said to be good for 79 percent of that.

Induction: A Mopar Performance M-1 single-plane intake mounts a Holley 950 HP Series carb, which is fed by a Carter high-perf electric fuel pump.

Valvetrain: A Comp Cams Xtreme Energy flat-tappet hydraulic cam with 250/256 degrees duration at 0.050 and 0.512/0.524-inch lift operates through the Indy 1.5:1 roller-rocker shaft assemblies.

Ignition: The ancient dual-point arrangement has been replaced with a Mopar Performance billet electronic distributor controlled with an MP "chrome box" module.

Exhaust: Tried-and-true Hooker Super Comp long-tubes with 2-inch primaries and 3-inch collectors send the spent gases to a custom-built stainless 3-inch exhaust system using Edelbrock stainless mufflers terminating just ahead of the axle.

Transmission: What would a Mopar drag car be without a reverse-manual-valvebody TorqueFlite? This one, built by TCI, is shifted through a Hurst Quarter Stick. The current converter is a 10-inch unit with 3,800-4,000 stall from the TCI Super Street Fighter series, but a custom converter is coming soon.

Rearend: Another mandate for hard-core strip Mopars is the Dana 60, though this one was actually created by Moser Engineering. It's been assembled using narrower-than-stock tubes and 35-spline axleshafts and has 4.30:1 gears on a limited-slip differential.

Front Suspension: The factory K-frame torsion-bar arrangement remains in place, though the bars themselves have been upgraded to MP 0.920-inch units. Everything has been rebuilt with parts from PST, and a Flaming River manual steering box lightens things up a bit.

Rear Suspension: Leaf springs have given way to a four-link from Chris Alston's Chassisworks, suspended with VariShock QuickSet coilovers.

Brakes: Any car that's aimed at the 10s or better should have something more than stock drum brakes to avoid the sandpit, and the Coronet uses Aerospace Components discs utilizing lightweight aluminum calipers on all four corners.

Body: The previous owner handled the paint and bodywork, replacing the stock hood, trunk, and bumpers with fiberglass pieces and covering most of the Dodge with '00 Corvette Millennium Yellow paint. Glenn replaced the Pro Stock-style hood and scoop with another 'glass unit mounting a Mopar-style Hemi scoop and had RG Custom in Riverside match the paint.

Wheels/Tires: For the modern drag look, Center Line Convo Pro wheels are utilized; fronts are 15x6 mounting Mickey Thompson Sportsmans in 28x7.50-15, while 15x15 rims hold the 29x18.50-15 Sportsmans out back for the street. Another pair of Convo Pros, this time in 15x14, are used with Hoosier Quick Time Pro DOT slicks in 31x16.50-15 for the track.
