The 351 Windsor is from the same engine family as the 260 / 289 / 302, but it has a deck height of 9.480″ – 9.530″. That means the 351W is almost an inch taller and 2 inches wider than a 260 / 289 / 302 with a deck height of 8.206″.

The 351 Cleveland (part of the “335” engine family) has a deck height of 9.206″ and is therefore not quite as tall or wide as the 351-W, but the heads have BIG staggered valves and are considerably larger.

Both the Windsor and Cleveland are 90 degree engines.
