1966 Ford Mustang Coupe - Devoted

It looks like a vintage 'Stang, but under the hood is EFI power.

Tech Notes
Who: David Lewis

What: '66 Ford Mustang coupe

Where: Wooster, Ohio, reportedly home to more Ph.D.s per capita than anywhere else in Ohio.

Engine: The block is a '92 5.0 topped with '69 351 Windsor heads. David doesn't know all the specs for the engine because he bought it already assembled from an eBay seller. He knew it had been recently rebuilt with high-compression pistons, roller rocker arms, and a really lumpy Crane camshaft. His college roommate convinced him to go with a fuel-injected engine. David had a '69 302 he was thinking of installing for a while.

Induction and fuel delivery: The hot-ticket intake for 5.0L guys is the GT40, and David's engine is no exception. He capped it off with a 75mm throttle body and 24-lb/hr fuel injectors.

Engine management: The donor car's wiring harness fit with little modification, so David used it rather than ordering an engine-swap harness. An X3Z computer from a '93 Cobra, stashed in the glovebox, keeps things running.

Exhaust: Headers were a no-brainer. David dropped in a pair of JBA shorties and connected them to a 211/42-inch exhaust system complemented by a pair of Jones Exhaust Systems Full Boar mufflers.

Ignition: Stock Duraspark. Nothing wrong with that.

Transmission: David modified the '66 crossmember to accept the donor car's Borg-Warner T5 trans. He works for LuK Automotive Systems as a quality engineer, so you can guess what brand clutch he's using. The driveshaft wouldn't fit, of course, so he ordered an aluminum one from Mustangs Plus.

Rearend: The rear axle is an 8-inch David also scored from eBay. It came out of a '66 fastback whose owner was upgrading to a 9-inch. He filled it with 3.55:1 gears on the factory limited-slip differential. The axles are stock.

Suspension: The car was originally a six-cylinder granny-mobile. Fortunately, David tossed all that stuff and rebuilt the front end to accept the manly V-8. He used GT Performance springs up front and exchanged the sagging leaf springs for OE replacement ones. He added traction bars to control spring wrap.

Chassis: David had to repair some areas of the floorpan that had been cobbled together by a previous owner. He installed homemade subframe connectors, then treated the chassis to a liberal coating of POR-15.

Brakes: Not satisfied with stopping distances that are best measured in yards, David swapped out the stock drum brakes in favor of four-wheel discs from Stainless Steel Brakes. He runs 14-inch rotors in front and 11-inch rotors on the rear.

Wheels/Tires: Those are 245/45ZR-17 Falken Ziex ZE-512 tires front and rear mounted on Bullitt-replica wheels from OE Performance Wheel.

Paint/Body: Jeff Kahl from Kahl's Kustoms in Mansfield, Ohio, welded on new quarters and massaged the creases and dings out of the remaining sheetmetal. He sprayed the body with Tungsten Grey, a color option on Mustangs starting with the '06 model-year. The LeMans and rocker stripes are done in Diamond White.
