Top 10 Engines of All Time (#9): Ford 351 Windsor
Ford Motor Co. introduced their Windsor small block engine family in 1962, releasing the 289 and 302 into the automotive wilderness.
As the public demand grew for more factory performance, the gang at Ford needed to figure out how to bridge their 302 and big block 390.
Enter the 351 Windsor.
Fun Fact
In 1970, just one year after introducing the 351 Windsor, Ford introduced the 351 Cleveland—an entirely different engine from the Windsor, but also displacing 351 cubic inches.
History
Ford debuted the 351 Windsor in the 1969 Ford Mustang Mach 1 with both two-barrel and four-barrel carburetor configurations.
The four-barrel variety disappeared after one year. And Ford continued to emasculate the engine as government mandates forced automakers to reduce power and fuel consumption. In 1978, Ford put small-valve 302 cylinder heads on the 351W and banished it to grocery getters and full-length vans.
But the 351W was the little engine that could.
And it was resurrected as a performance powerplant for later model Mustangs, though known mostly as the Ford 5.8L. And that’s when the automotive aftermarket started delivering power adders for this engine.
It was last seen coming out of the factory in the 1995 Cobra R.
The 351W still lives and is available as a crate engine from Ford Racing.

Can anyone tell me if a 351 Cleveland engine will fit in a dodge nitro engin bay.
The 351W continued in production past the 1995 Cobra. It was also used on the F-150 and Bronco through 1996 and a limited number of Super Duties and Vans in 1997.
Its potential would have never been fully known if not for the aftermarket. And its its not ford’351 with the greatest potential either. If the Cleveland were more readily available and had a larger following the aftermarket and ford builders would really be making a statement about Ford performance . The cleveland was built for high speed , high rpm and was halted and killed in its infancy by the new emissions regs . A little ride in bone stock boss 351 is all it takes to see what could have been if you understand what was going down at the time and the direction the cleveland pointed before getting neutered
I had a 1970 Ford LTD 2-door with the 351 Windsor, bone stock. What a pretty car, with its hidden headlights and aircraft-carrier hood length. The rear styling was a bit frumpy with those little tail lights. The truck was enormous, as was the interior. Back in the late-1970’s I used every but of that space driving to-and-from school with all my college-apartment stuff. And then, talk about reliability! The car never stranded me, ever. Plus, in any weather where the temperature was above 40°F, I could merely blip the key, and the engine would start. Some passengers weren’t sure if the engine even started it was so quiet. On Friday & Saturday nights you could flip over the air cleaner cover (all the intake air still passed through air filter, so it was safe to do). That resulted in the engine letting out this fantastic growl when punched, a sound that would turn heads.
My very first car at 16 (1984) was a ’69 Mustang coupe with a 351W and side loader 4 speed. Over the 10 years I had it, I went through the entire drivetrain front to back: Polished/ ported, huge vales in the heads, big cam, roller rockers, MSD electronic ignition, headers, top loader 4 speed, race clutch, 3.83 limited slip for the 9″ in the back. Etc, etc. Super reliable, and super fast on pump gas. I loved that car.
I kick myself in the backside almost every day for selling it.
