Before we leave the small-blocks behind there is one more to mention. The Boss 302 engine shown here is really a Windsor-Cleveland hybrid. The Boss 302 was produced for two years in 1969 and 1970. The specialized engine used the Cleveland cylinder heads, as clearly seen here, but the heads were used on a Windsor-architecture short-block specially designed for high rpm use. The Boss block had four-bolt main caps on journals two, three, and four, and it was the only vintage Ford 302 engine ever produced with a four-bolt block. The Boss 302 has assembled dimensions of 29Lx24 1/2Wx28 1/2H.
