Determining capacity of assembled engine?

[Bremith]

I have a complete engine with a number that indicates it started life in a 72T (2.4 - 911/57 casting). I'm told it's now a 2.7.

Are there any numbers I should be able to see to confirm without pulling the whole thing apart? Barrels? Heads? The barrels aren't steel, can't see a number on them but don't really know where to look either.

I believe you can get a displacement check done which will answer the question. Don't know much more though.

Thanks Neville.

No one out there with more P&C experience than me who can tell me how to check what cylinders are in there? Maybe if I pull the engine cover so I can see some names and numbers?

there is a difference in the number of cooling fins between a 2.4 cylinder and a 2.7, but at the moment i cant remember the details - 11 and 13 springs to mind but i am not sure
it must be searchable somewhere

Can you read any numbers on the bottom of the barrels?

I suggest that if the barrel fins encase the studs then it is 2.7 however if the fins terminate around the studs 2.2/2.4.
Hope that makes sense.

Pic from underneath - does this help?

i think i count 11 fins
here is a 2.4 Mahle that looks like 15 fins

so i think it is not 2.4 so most likely a 2.7

i tried to get a photo of my 2.7's but could not get enough light under the car to get a picture

84mm barrel in the foreground, larger barrel in the background.

And for fun Mahle and Kobbelschmit (KS) have different fin counts. KS are Alusil and Mahle are generally Nikasil. Both are 2.7l
