A 1960 Triumph TR3A rebuilt with a Ford Mustang 302 V8

Joseph Moticker converted his TR3A to run a 1988 Ford Mustang 302 V8 with a T5 five-speed and a narrowed Ford 8.8 rear end, fabricating his own crossmembers and moving the firewall to fit it all in. The result is a car he describes as fast and fun, finished in October 2013 and driven several hundred miles since. It is worth a look for the depth of home-fabricated chassis and interior work, including custom seats, roll hoop, and fuel tank.

How it was done

The swap

Moticker fitted a 1988 Ford Mustang 302 V8 into his 1960 TR3A, keeping the stock camshaft and cylinder heads but adding an Edelbrock intake and Holley carburetor. Ignition duties went to an MSD6AL box and Blaster 2 coil with Ford Racing plug wires, and he dressed the engine with a Cobra style aluminum air cleaner and valve covers.

Driveline

Behind the V8 sits a T5 five-speed gearbox using a Ford flywheel, pressure plate and clutch, actuated through Wilwood master and slave cylinders. Power reaches a narrowed Ford 8.8 inch rear housing fitted with a Traction-Lok limited slip differential, 4.1:1 gears, and billet axles on a 4x4.5 inch lug pattern.

Chassis fabrication

To fit the V8 and gearbox, Moticker replaced the stock front and transmission crossmembers with his own chrome-moly tubular fabrications and set the firewall back roughly two inches. Motor mounts were based on a Speedway Motors kit, and the clutch and brake pedals were shifted over about 1.5 inches to clear the new driveline.

Suspension and brakes

Up front he fitted a Brit Bits steering rack with heavy duty springs and KONI shocks. The rear kept the stock Triumph leafsprings, with an extra mid leaf added, and stock shock absorbers. Braking uses a Wilwood master cylinder with a remote reservoir, Toyota calipers and rotors up front, and Wilwood calipers and rotors at the rear.

Interior and safety

The cabin got hand rolled aluminum seats, covered in vinyl by a local upholsterer, a Grant GT steering wheel, Auto Meter Classic instruments, four point harnesses, and a custom roll hoop built by AC Car Craft in Oakland Park, Florida. A Lexan windshield was also fitted.

Body and finishing

The rear fenders were flared about one inch for tire clearance, and nearly all exterior trim was powder-coated black. An 8.5 gallon custom fuel tank was built with an electric fuel pump mounted in the trunk, and the car rides on Diamond Racing Pro-Street steel wheels with Fuzion 205/70R15 tires.

A summary in our own words. The full account, with all its detail, is the owner's: read it at britishv8.org ↗

Worth knowing

  • Fitting four point harnesses without anti-submarine straps leaves a safety gap.
  • Shoulder straps should not angle more than 30 degrees from horizontal per SCCA rules.
  • A roll hoop without padding or headrests can be uncomfortable and risky.
  • Moving the firewall back about two inches was necessary to make room for the V8.
