Default Ford engine classifications...

Something that's always bothered me is hearing people classify Ford engines as big blocks and small blocks.... true some are bigger than others, but there are no such animals as a Ford big, or small block... that was a Chevy thing.... Ford's are classified in series, or families....

as such...

Flathead series/family

136, 221, 329, 255, and 337

Lincoln Y series/family

279, 302, 332, 317, 341, and 368

Ford Y series/family

239, 256, 272, 292, and 312

FE series/family

332, 352, 360, 361, 390, 406, 410, 427, and 428..

FT series/family

330, 359, 361, 389, and 391..

MEL sereis/family

383, 410, 430, and 462..

Super Duty series/Family

401, 475, 477, and 534

90 Degree/Windsor series/family

221, 255, 260, 289, 302, and 351W

335 series/family

351C, 351M, and 400

385 series/family

370, 429, 460, and 514

Modular series/family Had this sent to me so thought I'd post it..

4.6, 5.4, 6.8

First 2 are V8 and the last one is a V10. Then there are various sub classes, 2,3,4 valve, Windsor or Romeo, etc. Not all combonations exist, no 4-valve 6.8 for example.

Then there is the new 6.2 hurricane V8. Too little info out there to tell if it falls into the mod motor class or not. Presumably not. It was designed on a wider bore spacing then the typical mod motors for increased bore size. But it may or may not be considered a mod motor in the future once we start learning more about it. Too new to really know anything about it.

There are a couple more V8s. The Taraus SHO V8 that was very short lived. Then there was a Jag that had a Ford V8 a couple years back.

There are the classifications of Ford engines, in the future when you hear some one call a 460 a big block, or a 302 a small block, or a 351C or M a big block, please point and laugh at them for doing so...

There are the classifications of Ford engines, in the future when you hear some one call a 460 a big block, or a 302 a small block, or a 351C or M a big block, please point and laugh at them for doing so...

Good question Russo, why dont you see what you can come up with and add it to this thread. Or make your own thread with the info in this section!

I'll see what I can do, I often do research on the inline six family and they are actually classified as big a small block 240 and 300 being big block and those smaller than that used long long ago were considered small blocks.
