the correct answer is windsor a crown vic never came with a Cleveland engine esspecialy in 91 that engine hasn't been produced since the early 80s
Windsor 351, is a small block. 351 Cleveland, is a big block. The 351M, stands for "modified" and is a windsor (small) block, with Cleveland (big block) heads.
Look on the value covers, windsor has 6 bolts. The cleveland has 8 bolts.
The easiest way to tell is that the Windsor has trapezoidal valve covers with six bolts, whereas the Cleveland has rectangular valve covers with eight bolts. Also Cleveland has the thermostat housing on the front of the engine and the Windsor has it on the intake.
The Windsor is a small block, basically an enlarged 289. The Cleveland is a big block, more high performance. You can tell the difference from the outside by looking at the valve cover. The Cleveland has 8 bolts securing it down * the Windsor has 5. Also the thermostat cover bolts to the block on a Cleveland and to the intake on a Windsor. Neil

If I remember correctly the 351 Windsor has a vertically mounted thermostat that is mounted in the end of the intake manifold The 351 Cleveland thermostat is mounted horizontally in the engine block by the distributor
6 degrees for a windsor and 10 degrees for a Cleveland
The 351 cubic inch V8 motor ( 5.8 Liters ) was manufactured in Windsor / Modified and Cleveland versions over the years
