Couldn't you tell by the stroke length? A 2.4 has a stroke of 72.7mm, the 2.6/2.8 is 79. Only 5mm, but it should be detectable.

Besides, aren't crank shafts forged, not cast?

yeah, they are forged, but they still have the numbers stamped into them so i suppose they can be casting numbers?

the human eye can see very small differences in size. Just set the crankshafts next to each other and i'm sure you'll be able to see the difference between them pretty quickly.

Get off the computer and go into your shed and check for yourself mate!!!

Don't slag off on others because you're too lazy.

Seriously, this board gets a lot of traffic. If no one replies to your topic for a full day it will be pushed off of the front page and never be seen by anyone who might have the answer you are looking to find.

Better to get a couple of snide remarks that bump your topic back onto the active page, than to miss the chance of someone who actually knows the answer never seeing your question.
