Believe it or not most of us here can do the math. Many manufacturers 'badge' their engine displacments somewhat differently from what the arithmatic would dictate so that their 'badge' displacement is different from their compeditor, etc. A Ford 302 is 301 point something cu in and is closer to 4.9L than 5.0L depending on how you round it. WHO CARES. If you refer to an engine by another name than what FORD called it YOU are the one that is confused/confusing.

...which was the maximum displacement allowed by NASCAR in the 1963 season.

...never said anyone here couldn't do the math; it's 4th grade stuff. I would hope that everyone here can do the math. I was just throwing out the fyi and then running the numbers for anyone who might care that hadn't taken the time to think about it.

Since you brought it up, the displacement of the 302 is 301.59; if you were going to round it to the nearest cubic inch, it would be a 302. The "302" is a 302 any way you slice it. The "427" is actually 425.

I was merely explaining why "425" was not a typo.

Now back to regularly scheduled thread topic.
