A little clarification.. (from memory not wiki)
Windsor generally refers to the small block family of engines produced at the Windsor Ontario plant..
Started with a 230cid? V8 in the 1961 Fairlane.. Ford never used the 'Windsor' designation, until the 351W had to be differentiated in parts manuals from the 351C 'Cleveland' pattern engine.. So when I use the term Windsor, I refer to all the SB fords of that pattern, not just the 351W..
Actually It was a pretty good motor for the early 60s.. Compact, and a bit lighter than it's arch rival the Small Block Chevy.. It always did well when paired with a 4 speed top loader, in a lightweight chassis, like Fairlane Comet Mustang Falcon, and the AC Cobra, Sunbeam Tiger, GT40..
LOL, Volvos too I guess!
The 289/4V in the 63 Fairlane/Comet chassis, with 4 on the floor, takes the credit for the 'first muscle car', beating the F85 Olds by 6mo, and the GTO by a year.. Carol Shelby built his whole legend by tuning 289 and 302s.. Creating a dynasty in Sportsman Road Racing that lasted thru most of the 60s, and a legacy that lasts to this day.. But no matter how good the Builder/Tuner, the head design was always the limiting factor..
While the old 60s Windsors may have been on the anemic side, modern alloy heads remove those limits on the ole Windsor.. And in the 60s, Fords made some MAGNIFICENT Big Block engines! So the 60s weren't all bad for Ford! Galaxy500 w 427SOHC and the Fairlane Thunderbolt for example!
The Cleveland was a whole leap ahead.. Many 351C guys have a set of 4V heads/manifold sitting under their workbench.. But USE the 2V heads, because they are more tractable in use, offering a more moderate power curve.. LOL, the 2V Cleveland heads flow as well as the Hiperf SB Chevy iron "Spike" 2.02 heads..
Ford actually produced relatively large numbers of the 4V Cleveland heads too, well into the mid 70s.. Grand Torino GT used em, and they were often found in those ugly "Elite" models.. Ford had to keep producing them for the public due to the Nascar 'homologation rule'.. After Nascar limited displacement to 352cid, the Cleveland 4V was the best engine goin.. Ford ruled until Chevy complained, and Nascar made the Fords use a restrictor plate, in the name of 'fairness'.. Ford kinda dropped out after that!
