Tom Thu's '67 Fastback

Tech Notes
Who:
Tom Thu

What: '67 Mustang fastback

Where: Maple Ridge, British Columbia, Canada

Engine: Tom has had a string of growing-displacement small-blocks between the shock towers of his '67, but the current one is the biggest and best yet. Built by Keith Craft Racing, the 408-inch Windsor stems from a '69 351 block using an Eagle crank and rods and coated Mahle pistons. Up top, ported AFR 205s sport 2.08/1.60 valves lifted by a Comp Cams hydraulic roller with 0.555/0.576-inch lift and 236/242 degrees duration at 0.050. In all, the engine dyno'd at 536 hp at 5,800 rpm and 551 lb-ft at 4,600 rpm.

Induction: There's nothing exotic on the intake side-a 780-cfm Quick Fuel Technology carb and a port-matched Edelbrock Performer RPM intake.

Ignition: MSD components are responsible for lighting the fire in Tom's 408 in the form of a billet distributor, a 6AL ignition box, and a Blaster 2 coil.

Exhaust: Ford Powertrain Applications makes the full-length headers found here featuring 1 3/4-inch primaries, ball-style collectors, and a tidy fit. They team with a 2 1/2-inch H-pipe, Flowmaster 40-series muffs, and stock-appearing GT quad tips.

Drivetrain: A Tremec TKO-600 five-speed is equipped with a 0.64 overdrive for effortless freeway cruising. The supporting cast includes a Ram billet steel flywheel, a hydraulically actuated 11-inch Centerforce clutch, and a heavy-duty driveshaft.

Suspension: A Randall's Rack and Pinion setup keeps the underpinnings from being completely old school, but there's little shame in the traditional when it works. To that end, Tom lowered the upper control arms for improved geometry and employed beefy 620-pound front coils, five-leaf rear springs, Magna front and rear sway bars, and urethane bushings.

Brakes: '60s tech disc/drum brakes were the stopping gear until recently, so the step up to Baer Pro Plus components was huge-literally and figuratively. Six-piston calipers and two-piece 13-inch drilled/slotted/zinc washed rotors are at all corners now, with the setup using an internal drum emergency brake and Lokar cables.

Wheels/Tires: The '67 rolls on much flashier stock than Bullitt did, yet the lineage of the polished 17x8-inch American Torq-Thrust IIs is clear. They did require some creativity to fit over the big, bad Baers, starting with 4.75 inches of backspacing and billet 1/2-inch spacers to clear the brakes. That's where Greens Automotive came into the picture, removing the wheel centers and increasing backspacing to 5.25 inches. The tires are BFGoodrich G-Force Sports, 235/45ZR17 up front and 275/40ZR17 out back.

Interior: Black threads are of the '67 Mustang deluxe variety, just as they were in '67 Shelbys. Upgrades include Auto Meter gauges, a Hurst stick, and a big Rockford Fosgate-powered stereo in case Tom gets tired of the small-block melody.

Paint/Body: Yeah, we know Tom's car is a slightly different color than Bullitt, reflecting Ford's change from '67's Dark Moss Green to '68's Highland Green. Mark Riches sprayed two-stage PPG products in the original hue, while Tom tackled the polishing. The Shelby-style 'glass trunk and endcaps were on the car when it was purchased, so their origins are unknown. The ribbed rear taillight panel is a reproduction of a rare optional '67 piece that few Mustangs were ever equipped with.
