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.
