5.0 or 4.6?

O.K. Technically then, the 4.6 is really 281.1 cid, not the 281 advertised but who's counting meaningless fractions? Not me.

Not really me, I was just pulling data out of a Chilton's manual. It's not like I was posting to prove somebody wrong. In fact, the data I gave is either rounded, or wrong. I don't know if the 4.6L's bore and stroke is technically recorded in cubic centimeters and then converted to inches, or whether the engine is technically not 281ci. The bore and stroke I gave would give an answer of 280.31ci. If you went by the 4601cc's then converted it back to ci, you'd have 280.77. Which would then round to 281.

Either the specs I have are wrong, or I'm just incorrect in attempting to figure out displacement? Maybe Ford uses significant digits or something. I really hate those.
