* All 400s were low-performance engines that ran on regular fuel and all used a 2-barrel carburetor, a cast-iron intake manifold, and small port 2V cylinder heads. The cylinder heads for the 400 were the same as those used on the 351C-2V, having the open combustion chamber with smaller 2V sized ports and valves. The 400 featured larger 3.00-inch main bearing journals, the same size as those used in the 351 Windsor, but rod journals were the same size as the 351C. As a result, the 400 used longer (6.580″) connecting rods than the 351C (5.778″), but it retained the same connecting rod-to-stroke (1.65:1) ratio as the 351C. To accommodate the longer stroke, Ford engineers increase the block deck height to 10.297 inches compared to the 351C’s 9.206 inches. Ford called the engine 400 cu in but it actually displaced 402 cu in (6.6 L). The 400 had “square” proportions, with a 4.0 in (102 mm) bore and stroke. It had a half-inch (12.7 mm) longer stroke than the 351 Cleveland, making it the longest-stroke Ford pushrod V8 engine. The Ford 400 engine was based on the 351 Cleveland.

It was designed to provide brisk acceleration in medium to heavyweight vehicles in an engine package that was smaller and lighter than the FE V8 Engines and the 385 Series Ford V8’s. Ford billed the 400 as the 351C’s big brother. With pending emission requirements, a more modern replacement was needed.Īlthough the big-block 385 family was used to replace the larger displacement 428 V8 FE engine, this engine family had nothing comparable in size to the 390 V8.įor the 1971 model year, Ford introduced the 400 V8 engine as a replacement for the 390 V8. By 1970 the 390 V8 FE engine was becoming outdated.
