engine block year??
I want to swap the 250 crossflow for a 351 in my XD.
I know that it is a hell of a lot easier to just sell the XD six and buy an XD eight but this one has a family history.
Anyway, my questions are;
Does an engine block have any way of telling what year it is?
I ask this because I don't want to buy a reconditioned 351 and find out it was from an XY and then have the Qld department of transport tell me the engine is older than the car and therefore won't pass emissions.
Does the year of the block matter anyway?
And if so, what 351 block should I be chasing? Pref. 4 bolt.
Thanks for any info you might have,
