Conversion performed by: Owner
|Engine:||Ford 302 bored out to 310ci, and completely rebuilt. Aluminum high-compression pistons
are used with 1/16th" chrome-moly rings. A mild Crane cam (towing grind) is used. A heavy
duty oil pump and shaft helps to prolong engine life.
|Intake:||A Holley 600cfm 4 barrel carburetor sits on an Edlebrock Torquer II manifold, and breathes
through a side draft air cleaner. A heat shield is slipped between the carburetor and the manifold.
|Engine Electrical:||An Accel distributor feeds an electronic ignition system and a high output coil.
|Drivetrain:||Transmission is a BW T5 World Class 5-speed with a Hurst shifter. A Centerforce
dual-friction clutch is actuated by a Tilton hydraulic throw-out bearing. Power is sent
to the rear by way of a custom made 21/2" drive shaft.
|Cooling:||A Stewart Stage 1 water pump circulates coolant through a Griffin cross-flow radiator,
where it is cooled by a 16" electric cooling fan in a "pusher" configuration. A fan shroud
is provided to ensure all the air flows through the radiator instead of around it.
|Exhaust:||Sanderson street rod headers, ceramic coated, send the spent gases through a custom
made stainless steel exhaust system.
|Rear axle:||The stock IRS differential is retained, but it has been rebuilt, as have the rear hub
assemblies, with new U-joints all around. The differential is now suspended with
polyurethane bushings. The differential mounting brackets have been reinforced.
|Front Suspension:||KYB shocks are used, along with new springs and polyurethane bushings. A new sway
bar was fitted.
|Rear Suspension:||Lever action shocks have been replaced with a tube shock conversion. New springs
and polyurethane bushings are used, along with a rear sway bar.
|Brakes:||A complete new brake system has been installed - M/C, wheel cylinders, brake lines,
pads, discs, and drums - and braided stainless steel lines are used for the flex-lines.
Toyota 4-pot calipers are used in front, and 7/8" Sunbeam Alpine rear wheel cylinders
are used. Brake fluid is Silicon DOT5.
|Wheels/Tires:||Pirelli P6000 Sport Veloce 215/65/R15 tires are fitted to 15X6 Panasport aluminum wheels.
|Interior:||Seat rebuilt with new foam, diaphragms, and leather seat covers. New carpets installed,
with double underlay and heat shield. Dash has been re-veneered and an Alpine stereo system
added. For comfort, fresh air ducts vent cool air to the footwells. The old top has been
replaced with new.
|Body/Paint:||Six coats of Sikkens "Rio Red" acrylic urethane paint.
|Electrical:||GM alternator replaces the anemic Lucas unit. All wiring bullets have been replaced.
Headlamps are now Halogen.
|Fasteners:||All load bearing points have grade 8 fasteners. All other points are stainless steel.
