Tech Notes
What: A '70 Ford Mustang Mach 1
Owner: Bobby Curtis
Hometown: Renton, Washington, just south of Seattle.

Occupation: He is part owner and parts-and-service director for two Infiniti dealerships in the Seattle area.

Saga: He blew up the engine within the first hour of ownership. He stripped the interior, frontend, and everything but the sheetmetal. He had a guy come over to finish the wet-sanding and polishing of the body while Bobby went through the drivetrain.

Brakes: The car didn't want to stop, so he replaced the stock parts with a Baer 13-inch Track system for Mustangs. He said it just bolted in behind the 17s.

Engine: The 351 Windsor has the numbers-matching block bored 0.030-over. It went to a machine shop to have the block checked and came back with an 11.0:1 rotator and an Honest Performance mystery cam. Bobby bolted on the Victor Jr. heads, the intake, the Speed Demon 850 carb, and the MSD ignition stuff.

Exhaust draggin: The set that came with the car was cracked, so on went the Hooker Super Comp long tubes after they were ceramic coated. The Mustang has 3-inch pipes back to the Flowmasters with tips from MagnaFlow.

Wheels: The car came with 17-inch Edelbrock 454s. He had them rechromed and added the Pirelli P Zero Rossos, 235/45R17 front and 245/45R17 rear.

Front suspension: When he first drove the car, it was all over the place with the 17-inch wheels on it. After surveying some local import tuner kids, he decided to use a Total Control Products rack-and-pinion steering setup. After a little mounting-bracket refab, the kit bolted right in. He says, "It still won't steer like a new Infiniti. It's a handful but a lot better."

The pump: Bobby bought it with the power-steering rack from Total Control. It was sold separately and was valved for high-speed track action, so the wheel needed a lot of effort to turn. Now it's valved to turn corners and park.

Rear suspension: He went through the 9-inch rearend and added the factory Traction-Lok from Northwest Differential he found on, yes, eBay. He kept the 3.00 gear that was in there and added some Shelby traction bars.

Paint: Brilliant Silver to match his hair. The original owner painted the stripes.

Transmission: To get the Tremec five-speed to work, Bobby bought a clutch and brake-pedal assembly out of a four-speed car. Then he cut a hole in the firewall for the clutch master cylinder and attached the pushrod directly to the pedal arm. The slave, bellhousing, and gearbox just bolted right in. He purchased the Tremec kit from Dark Horse Performance in Renton, Washington. The headers go on last.

Interior: Everything is either eBay or Mustangs Unlimited. The clock was purchased already refurbished, and Sunmark Upholstery in Kirkland, Washington, recovered the seats.

Tricky stuff: For the factory tach to work, he used an MSD tach adapter. He still needed the original harness to get everything else to work properly, so he bought one on eBay already rebuilt.

Power: On the dyno, he saw 485 hp and 425 lb-ft at 6,000. We're thinking the cam is big.

Stupid stuff: He won First Place in the Street Modified class at the Mustang Round Up in Seattle, then during some other photo shoot, he drained the battery with the lights on and the door open. Then had to steal a battery out of a 'Cuda to make our shoot. All at a Ford show.
