PPG black cherry metalic with ghost panals front and rear. The majority of lower chrome body trim and emblems have been removed or painted.
  • Hotrock is a 1972 Mercury Comet; an original 302ci car. 1 of 34 Comet 2 door sedans built with paint code 2B (Bright Red), Trim Code KA (Black Vinyl Bench Seat) and (Black Vinyl Top). The bench seat in combination with the black vinyl roof is what makes Hotrock a rare Comet. Of those 34, only 3 were built with the handling suspension. Of those 3 only 1 was built with optional D70x14 belted Firestone Wide Oval tires. Hotrock is that Comet.

    Hotrock now sports a Comet GT hood with a functioning scoop, tinted glass, and painted PPG black cherry metallic with ghost panels front and rear. Most of the chrome and emblems have either been removed or painted the body color.

    Powered by a modified 351W for many years, Hotrock is now motivated by a 302ci `91 roller engine. It has a stock crank and rods clamped with ARP bolts and Keith Black flat top lightweight pistons. Trick Flow Stage II roller camshaft and Crane 1.6 roller rockers. A set of Air Flow Research 165cc Competition Package heads are milled to 54cc. for a 10.1:1 scr. A Weiand Stealth dual-plane intake manifold with a 1" open spacer and a Speed Demon 750 vacuum secondary carburetor handle the fueling. To make spark, a Ford Dura Spark ignition system utilizes a genuine Motorcraft module that has been in service for more than 25 years . Hooker full length headers, Flow Master mufflers with custom bent 2 1/4 inch duals passed the rear bumper complete the exhaust system.

    A slightly modified C4 transmission utilizing a Summit Racing 3,500 stall convertor is manually shifted during competition at 6,500 RPM. The stock 8" differential with a 3:80 traction-lok completes the drivetrain.

    The suspension is a mostly stock configuration other than an Addco 7/8" front sway bar, gas shocks front and rear along with three leaf rear springs. Welded on Summit Racing sub-frame connectors reduce torque twist, while CalTracs bars keep the Mickey Thompson drag radials planted.

    Hotrock is street and highway driven, never trailered. 1/4 mile performance : 12.50s @ 109+mph.

    Closed headers and full exhaust at Quaker City Raceway. Turn up your speakers.

    Hotrock and my son's Terminator face off at Thompson Raceway Park with a winning 12.6 ET. It takes more than a super charger to get through the traps first.

    Hotrock vs a Z28 Camaro Quaker City Raceway June 24, 2015 13.16 ET at 106.18. I had a 2500 stall convertor at that time. 3:80 gears are not the best for drag racing with this combination. You can see and hear that I'm almost through the traps when shifting into third at 6,500 RPM; about the equivalent of a two speed transmission.

    I like the photo near the end of the following group where I'm lined up with the Hemi Charger at Dragway 42. The Charger lost!
