How Do You Identify A 351 Cleveland?
Identifying a 351 Cleveland is more a matter of telling the difference between the 351 Cleveland and the 351 Windsor. Both are strong engines, and the few traits used to differentiate between the two are found in the engine’s heads, which means you have to remove the valve cover and the head to make measurements as well as look at the configuration of the combustion chambers. Because the engines are so similar, both checks must be completed for a definite answer. Use the socket set to remove one valve cover and one head from the engine. Be sure to place the bolts in a safe place to avoid losing them. Look at the heads. The 351 Cleveland (usually called the “351-C”) 4V has larger ports than the 351 Windsor (the “351-W”) or the 351-C 2V, meaning that the exhaust and intake manifolds are different from the 351 Windsor. Starting in 1970, all 4V engines were Cleveland-based. Identify the configuration of the combustion chambers, measure their width and depth with calipers, then calculate th
