Ford 360 FE specs: 360 ci (5.9L) 8-cylinder, 4.05 x 3.50 in (102.9 x 88.9 mm) bore and stroke. OHV, cast iron block. Rod ratio and piston speed worked out.
The Ford 360 FE is oversquare — the 4.05" bore exceeds the 3.5" stroke by 15.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.5" stroke puts mean piston speed at 4,000 ft/min around 6,850 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 45.0 ci (737 cc).
It is one of 3 engines in the FE family, all of them 360 ci — the differences between them are in compression, heads and rating, not displacement.
| Displacement | 360 ci / 5.9 L |
|---|---|
| Bore | 4.05" |
| Stroke | 3.5" |
| Cylinders | 8 |
| Bore/stroke ratio | 1.157 |
| Block material | cast iron |
|---|---|
| Valvetrain | OHV |
| Fuel type | gas |
| Bore/stroke character | 1.157 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves |
|---|---|
| Mean piston speed at 6,000 RPM | 3,500 ft/min — conservative for a street engine |
| Displacement per cylinder | 45.0 ci |
