Does anybody know how much of a difference it would make if I swapped the engine in my XF from a standard 4.1l carby to a 4.1l carby 250 crossflow?
The 250 X-flow has only done 70,000kms and has apparently been blueprinted. It has also been sitting for 6 months, is this a major problem?
My XF's current engine has done 255,000kms and hasn't had much work done to it apart from frequent servicing.
Is there an easy way to tell if an engine has been blueprinted? As I would like to make sure before purchasing.
Any info would be handy.
