What is a typical engine life???

[saber]

As the title suggested, what would be the typical engine life of a ford falcon? This topic has always interested me since I got my first car off the old man (1990 XF ute, gave it to me with 410000km, now up to 495xxx). With the great advancements in electroics and precision engineering I would have thought the engine life would have dramatically increased.

I was also told that a V8 engine should last many more Km's than a 6 (either V6 or i6), due to the 8 cylinders in a V8 firing less times per cylinder that a 6. For example, say we a cruising at 2000rpm, this equals 33.33 revs per sec, or 5.55revs per cyclinder per sec for a 6. Now in a V8 at the same revs we would be revolving at 4.167 revs per cyclinder per sec. I know that we wont always be at 2000rpm, but in general, at any rpm, a 8 cyclinder engine will be revolving less times per cyclinder than a 6, hence a increase of engine life. So considering this, do you think a 8c engine has a greater life than a 6???

What are you opinions?
