2.0L or 2.5L

[perreau]

Hi guys, i have a 150 V6 carb Merc and we suspect it is a 2.5L block though its listed as 2.0

My serial is D167071 and my Casting number on the cylinder head is 884-9765-C1

Can you please advise which block it is?

Cheers.

That serial number is a 2.0, the casting number could be a XR2 engine but no way of saying for sure.

Thanks, so there's no way this is a 2.5L block right?
