I have the new 4.6 emblems and it will be a bit before I install them. I gotta get the bodyshop to fix a few things first. Now that my paint has cured for a month they have some areas to repair that they didn't do correctly.

Should post them within a couple of weeks.

Wrong.

289 was a pushrod engine, older brother to the 302.

The 4.6 is a 281.

Hey Susan :tongue:,

The 289 (and it's bored sibling, the 302) is the venerable V8 used by Ford since the 1960s. To convert cubic inches to cubic centimeters (divided by 1000 for liters), multiply the cubic inches by 16.38, or divide the liter number by the same. A 289 yields 4733.82 cc (4.7L). Hence, the 4.6L (4600 cc, not exact but close enough) is actually 280.83 ci or 281 ci.

How about this...a 302 ci motor (the old 5.0) is actually 4946.76 cc. Rounded properly, it's really a 4.9, not a 5.0!! :eek:

Heh, I've been over that a few times with some others. Someone suggested "mathematical rounding" from 4946.76 to 4947 to 4950 to 5000 hence 5.0.

Of course mathematical rounding only rounds once.

So since us 281'ers have a 4602.78 why don't we have a 4.7? ;)

But yeah, you are right, just like Intel and AMD have done for years it gets rounded up to the next nice full number.

On a side note though, with mathematical rounding a 302 is a five liter engine, it's just not really a 5.0 ;)
