The Ford 351M and 400 cubic inch V8 engines are members of the Cleveland, or 335 series family of Ford engines. The 400M was first introduced in the 1971 Full-size model cars and station wagons. It was developed as an economical, reduced emissions replacement for the larger, gas-guzzling 429/460 and the ageing 360/390/428 V8 engines. The 351M was developed in 1975 to replace the 351C for use in large passenger cars. The 351M/400 engines were used in light-duty trucks starting in the 1977 model year.
Ford Engineers developed the 400 engine in response to the new Government pollutions requirements that were to start in the 1971 model year. Ford needed a tough, “workhorse” that was small enough to meet the new Government regulations and yet rugged enough to push around a 5,000 Lb Country Squire station wagon loaded down with another 1,000 pounds of passengers and luggage for 100,000 or more miles! The FE series (360/390/428) engines were terribly outdated (13 years old by 1971), and would have never been able to meet the new pollution and gas mileage restrictions required for the 1971 automobiles. The smaller 302 and 351 Windsor engines could have done the job, however, these engines were designed for higher RPM duty in small to mid-size passenger cars. Ford needed a whole new engine to do the job.
