| 1993-1995 - 5.8 L Windsor V8, FI, 240 hp Lightning
The 351W is often confused with the 351 Cleveland, which is a separate engine of similar displacement
The 351 Windsor featured a 1.5 in (38.1 mm) taller deck height, allowing a stroke of 3.5 in (88.9 mm). Although related in general configuration to the 289-302 and sharing the same bell housing and other small parts, the 351W had a unique, tall deck block, larger main bearing caps, thicker, longer connecting rods, and a distinct firing order, adding some 25 lb (11 kg) to the engine's dry weight. The distributor is slightly different to accommodate a larger oil pump shaft and larger oil pump. Some years had threaded dipstick tubes. It had a unique head which optimized torque over high-rpm breathing, frequently replaced by enthusiasts with aftermarket heads providing better performance. Early 1969 and 1970 heads had larger valves and ports for better performance. Early blocks, as with all SBF, were superior in strength to most late model, lightweight castings.
Introduced in 1969, it was initially rated (SAE gross) at 250 hp (186 kW) with a two-barrel carburetor or 290 hp (216 kW) with a four-barrel. When Ford switched to net power ratings in 1972 it was rated at 153 to 161 hp (114 to 120 kW), although actual, installed horsepower was only fractionally lower than in 1971.
The 351W was produced from 1969 to 1997. It was installed in everything from Mustangs to the full-size cars, and all the way up to the F350. It has been one of Ford's most successful engines. |
