Today it’s common to find engines from several manufacturers that share displacement figures. Engineers determined that 500 cc per cylinder is a sweet spot for efficiency with low emissions and, consequently, there are lots of 2.0-liter four-cylinders, 3.0-liter sixes, and 4.0-liter V-8s. Before that discovery, road taxes in some countries also influenced displacement. Plenty of manufacturers ended up with engines designed to fit under certain mandated thresholds.

You mentioned the Pontiac 400 in the 428 section, but not in the 400 section. The Pontiac 400 was first used in 1967, replacing the 389, and it continued in use well into the 1970s. How did you miss that?
Packard had a 352 cubic inch V8, as did Ford. Before their V8's in 1955, Packard had a 327 cubic inch straight 8 - match to displacement of Chevy 327 V8 - and a 288 cubic inch straight 8 - close to a Ford or Studebaker 289 V8 in displacement.
The 383 was an option on 1967-69 Darts (GTS). I think Mopar when I hear 383, too. Maybe 383 is a Chevy thing in the drag racing crowd, but I never heard of it before.
The 383 was a Mopar engine, used in most mid and full size cars and trucks in the 60s and 70s, including Barracuda, GTX, etc. Pontiac also had a 426 in the 60s in its full size models.
And optional in Wildcats and Electras when introduced in 1962. 425 was standard in the 66 Riviera only. 66 was the first and only year the "new" Rochester Quadrajet carb was used on the nailhead. Same carb was used on the 65 Chevy 325hp engine.
Didn't see the 425. Article says the 401 was the biggest Buick "nailhead". The 425 was. Produced from 1962 -66.Also, the 425 Olds from 65-67(?) and the 425 Caddy from 77-80(?).
Just picking a few ranges....
in the 300ci range
302 Ford, Chevy, Lincoln/Ford
307 Chevy, Olds
in the 320's
331 Cadillac, Chrysler
425 Olds, Cadillac, Buick
427 Ford, Chevy (2)
428 Ford, Pontiac
429 Ford (2)
430 Buick, Mercury
There is a 3rd 351 variant. The 351M for modified looks like a 351C but the two engines have very little in common. I'm not sure if he heads or intakes (2bbl engine or 4 bbl engine) will interchange but the 351M block shares it's design with the 4"x4" 400M, has a different bolt pattern for the transmission and motor mounts are different. It even takes a different starter. A transmission for the 429 and 460 big blocks as well as the starter bolts to the modified block. I believe the fuel pump is the only thing the Modified block has with the Cleveland.
Yes, even though Ford called it a "Modified Cleveland", and the 400 is also considered to be in the Cleveland family, neither engine is very much like the original Cleveland, which was a great performance machine. Yes, the M is considered a big block, which is why it uses the transmissions and bellhousings with the big block pattern. I consider it an engine built with low compression in response to the newer emissions standards, and generally and undesirable mill, unless you want to do major mods to it. I don't believe it came in anything other than pickups, and only with a 2-barrel carb.
