Block
The 5602 cc Tickford V8 engine had a cast iron block with 101.6 mm bores and an 86.4 mm stroke, increased from 76.2 mm for the 4942 cc Windsor V8. As an overhead valve (OHV) engine, the camshaft was located inside the block and positioned close to the crankshaft so that it was driven by a shorter chain.
Crankshaft and connecting rods
The Tickford V8 engine had a nodular iron crankshaft, shot-peened billet connecting rods and short-skirt, floating gudgeon pistons.
Cylinder head and valvetrain
The Tickford V8 engine had a cast iron, ported and machined GT40P cylinder head with two valves per cylinder and double valve springs. The valvetrain for the Tickford V8 was shared with the post-April 2001 220 kW Windsor V8; as such, it had:
- Yella Terra 1.72:1 roller rockers;
- 49.3 mm diameter inlet valves;
- 39.4 mm diameter exhaust valves;
- 11.9 mm inlet valve lift; and,
- 12.0 mm exhaust valve lift.
The camshaft, however, was unique and provided the 250 kW Tickford V8 engine with an intake duration of 276 degrees, exhaust duration of 266 degrees and valve overlap of 39 degrees.

Intake
To maximise intake airflow, the 5.6-litre Tickford V8 engine had:
- A three-piece, high-flow inlet manifold;
- A conical air cleaner; and,
- An 82 mm diameter throttle body (up from 70 mm for the 220 kW Windsor V8).
The Tickford V8 engine also had a dedicated mass air flow sensor.
Injection and ignition
The Tickford V8 engine had electronic multi-point fuel injection; pressure for the fuel system was 4.3 bar (up from 2.8 bar for the 220 kW Windsor V8). Controlled by Ford’s ‘EEC V’ engine management system, the Tickford V8 had distributorless ignition via centralised platinum spark plugs.
The firing order for the Windsor V8 engine was 1-3-7-2-6-5-4-8, while the compression ratio was 9.6:1.
Lubrication
The 5.6-litre Tickford V8 engine was fitted with an oil cooler as standard and required Mobil 1 0W40 synthetic engine oil.
