SHELBY 427 FE ALUMINUM HEADS

Shelby FE Aluminum Cylinders Heads

Shelby FE Aluminum Heads are cast from A-356 aluminum, heat treated to T-6 hardness level and precision CNC machined. pattered on Ford's famous 427 FE medium-raiser cast iron heads, Shelby FE offers leading edge air flow improvements, starting with standards 2.250- inch intake and 1.750-inch exhaust valve diameters. Due to valve size, heads are suitable only for Shelby 427 Alloy FE or factory 427 cast iron blocks. Heads utilize a 14mm diameter,3/4 -inch reach, gasketed spark plugs positioned in the stock location. they are sold in pairs, complete or bare. Bare heads come with ready-to-run valve seats, so you just add valve components and go. All Shelby heads are pressure checked.

• Modified intake port short turn radius along with valve bowl area for improved air flow quantity and quality. Ample port wall thickness allows rooms for additional porting.
• Exhaust port floor is raised 0.250-inch for improved exhaust flow velocity.
• Manganese bronze valve guides provide superior heat transfer and oil retention for proper valve stem lubrication.
• A cast-in "bridge" in the coolant passage openings, add strength. Deck surface is 5/8-inch thick.

Valve Components

Shelby can supply complete valve components for Shelby aluminum or factory cast iron FE heads. This includes one piece stainless steel valves with swirl polished heads and under cut stems. In addition, steel or titanium valve retainers and machined valve locks are available, along with valve springs to fit any custom valve train application.

Shelby 427 FE Single plane intake manifold

For horsepower hotter than Carroll's famous chili, Shelby's 427 FE single plane intake delivers race track power in a 2000-7500 and higher rpm range. This aluminum manifold is ideal for drag or racing or any maximum horsepower application where hood clearance isn't an issue. This manifold fits Shelby FE Aluminum heads and factory 390/406/427/428 cast iron FE heads.

FE Distributor and ignition Components

Breakless electronic FE distributors for Shelby blocks and factory cast iron blocks are offered. Unlike rebuilt factory distributors, these new distributors housings offer superior distributor shaft support for accurate spark timing at over 6500rpm.Magnetic breakless control provides precise spark timings and are maintenance free. compatible electronic ignition systems capable of generating the hot spark mandatory for high performance are available. replacement distributor caps and rotors are also available.

Shelby FE oil pan

Also available is a cobra race oil pan with internal baffles designed to keep the oil pickup submerged in oil during hard cornering and braking. The pan is also equipped with a windage tray and scraper to minimize oil mist parasitic power loss created by the spinning crank. Dip stick tube is located on the front passenger side of the pan. Oil pan fits Shelby FE Alloy blocks and cast iron FE blocks.

Shelby FE Oil Pumps

Oil pumps are available in standard and high pressure or volume versions. They have a black phosphate coating to eliminate corrosion and a rigid cover plate precision machined for flatness in relation to the pump gears. Inlet and outlet port dimensions are increased for improved flow. A chrome oil pump drive shaft is also offered. Pumps fit Shelby and cast iron FE Blocks.
