You also missed 421 and 425. If you do 440, 454, 455 and 460 I'm going to get worried.

I saw somewhere that the Ford 427 was actually a 425, but Ford wanted it to be called a 427. I haven't done the math to check this out.

OK - MAYBE a Belated 421 Day thread but 425 - nope. And before you bring it up, yes, next year you will see a 327 Day thread. Count on it!

It's neat how you can just make out the Mach 1 stripe on the Boss 429 prototype in the winter/spring Michigan pic.

Those shock towers caved on ALL the V8 Mustangs, even the small blocks, unless reinforced some way. All those early Mustangs were virtually impossible to keep aligned without doing some mods. Really hard on tires.
