What is the Difference between a 351 Cleveland And a 351 Cobra Jet
The351 Cleveland and 351 Cobra Jet are two high performance V8 engines that were produced by Ford. Both engines were based on the small block Ford V8, but there are some key differences between them.
The 351 Cleveland was introduced in 1969 and was produced until 1974.
It was a larger engine than the standard small block Ford V8, with a displacement of 4.0 L (242 cu in). The351 Cleveland had a cast iron block and heads, with hydraulic lifters and pushrod-operated valves. It used a carburetor for fuel delivery, and had a compression ratio of 8.4:1.
The power output of the 351 Cleveland ranged from300 hp to 400 hp, depending on the version. The 351 Cobra Jet was introduced in 1968 and was produced until 1971. It had a displacement of 4.1 L (250 cu in) and used an aluminum intake manifold to save weight.
The351 Cobra Jet also used carburetors for fuel delivery, but it had a higher compression ratio of 9:1. This resulted in an increased power output of 335 hp to 428 hp depending on the version. So, what’s the difference between these two engines?
Well, the biggest difference is in their size – the 351 Cleveland is slightly larger than the351 Cobra Jet. However, this doesn’t necessarily mean that the 351 Cleveland is more powerful – while it does have more potential power, the actual power output will depend on how it’s been tuned or modified.
How Do I Know What 351 Motor I Have?
There are a few ways to identify what 351 motor you have. One way is by the casting number on the engine block. Ford used different casting numbers for their351 engines throughout production.
Another way to identify your engine is by the vehicle it came in. The Ford Mustang was available with a351 Windsor engine from 1969-1973. The Bronco, Fairlane, Galaxie 500, and Ranchero were also available with a 351 Windsor engine during various years of production.
Finally, you can identify your 351 engine by its dimensions. The Windsor has a smaller bore than the Cleveland and will measure at 4” x 3.500”.

The 351 Cleveland Cobra Jet (CJ) was a high-performance V8 engine offered by Ford Motor Company in its muscle cars of the late 1960s and early 1970s. The CJ used a larger carburetor and had revised intake and exhaust manifolds, compared to the standard production 351 CID engine. It was created to compete with Chrysler’s Hemi engine in drag racing.
The first Cobra Jets were available in 428 cu in (7 L) displacement; however, only 50 units were built with this size. In response to customer demand and after consulting racers such as “Dyno” Don Nicholson, Ford increased the displacement of the engine for 1969 to 460 cu in (7.5 L). A total of 1,357 units were built that year.
For 1970, an improved version called the Super Cobra Jet was offered which included stronger connecting rods, forged pistons instead of cast ones, larger valves, and an improved camshaft. That year saw 3,163 SCJ engines produced.
