and the Ford 428’s bore and stroke measured 4.132 x 3.984 inches, which equals 427.386 cubic inches. Yes, you read that right—the 428 is a 427! Because Ford already had a 427 of sorts, the folks at Dearborn simply rounded up.
and the Pontiac 428 wasn’t quite what it seemed. When you account for the 4.12-inch bore and 4.0-inch stroke, actual displacement comes out to 426.613 cubic inches.
The Pontiac 350 was a 3.875-inch bore and 3.746-inch stroke, which doesn’t equal 350 cubic inches, it yields 353.42.
and because of the cubic-inch rules at General Motors, for smaller cars, the limit was 330 cubic inches, so Pontiac called the 336 a 326.

Interesting factoids Jesse. Now I know my Firebird's 350 is actually a 352.42 C.I. engine. Hmm, this is going to be trick to change the 350 badge on the hood. Didn't Ford have a 352 OHV big Y block back in the late 50's?

DeleteThe Ford 302 V8 (301.6 cu. in) displaced 4942 cc, which was also rounded up to 5.0L.
