KMP393: brushed alum coachwork/polished stripes

A serpentine Secretariat: shot above is hotlinked [same view, MUCH larger size].

Kirkham Motorsports KMP427 S/C Cobra replica. KMP393 is a splendidly handcrafted aluminum coachwork masterpiece. It's very similar in appearance to the 2003 Ford Motor Company show car built by Kirkhams. The stripes are polished into the metal itself for a rich, deep appearance.

The powerplant: built from an original factory replacement cast-iron 427FE side-oiler block with only the best componentry. Edelbrock aluminum heads ported by Keith Craft Racing who also supplied the hydraulic roller camshaft. Bored & stroked to 482 cubic inches, the throttle must be nudged like a rheostat rather than as an on/off switch.

Geartrain: Tremec TKO600 close-ratio 5-speed transmission with a hydraulic clutch that activates a billet aluminum clutch fork [to put the kibosh on any potential oil-on-clutch material problems]. Original-style (Salisbury type) IRS. Everything operates through Kirkham's beautiful billet aluminum suspension. This is a "Bucket-List" drivin' machine in every respect.


This Cobra is titled in Idaho as a 1965 Cobra replica.

   Here are some particulars about this extraordinary Kirkham Cobra...

The original/NOS 427FE side-oiler block was found still in the original FoMoCo crate and then built from the finest of components:

  • Diamond pistons with K1 connecting rods on a Scat 4.250"-stroke crankshaft
  • Armando 10-qt. Aviad-style oil pan
  • Holley 750 cfm vacuum secondary carburetor
  • Edelbrock 'Performer RPM' intake manifold
  • Edelbrock aluminum heads expertly ported by Keith Craft Racing
  • Erson roller rockers on T&D shafts
  • Comp Cams camshaft
  • Crane hydraulic roller lifters with Smiths pushrods
  • Pertronix ignition with a Melonized drive gear—so no unusual wear with the roller cam, and no need to routinely replace a brass drive gear
  • broken in and the carb tuned on the dyno [538 hp@5,400 rpm; 565 ft.lbs. torque@4,100 rpm]
  • Edelbrock water pump
  • Mocal oil cooler with thermostat for quick warm-up
  • Kirkham billet engine mounts

I've possessed KMP393 since 2005. I wanted to do the finish work so I took quite a while to get everything completed. The original headers were just not up to my exacting standards, so in 2016 I had new headers custom built by Tom at Tom's Motorsports in Las Vegas. They are beautifully crafted and ceramic-coated along with the sidepipes. Tom also sorted out the suspension and now it's (even more) terrific to drive.

Presently this immaculate serpent has logged a total of only 590 miles [950 km].
