Surprise finding in the engine compartment

[Vinyl66]

I took off the starter tonight to ID the engine in my new '66 coupe that I was told had a mid 90's block in it. They were wrong!

The ID #'s read D1ZM-6015-AA

This is the much sought after Mexican block with 289 Hi-Po style bearing caps, thicker cylinder skirts, and higher nickel content alloy. This would be a great platform for a 347 stroker in the future. It should stay together in a high horse application.

Does anyone here have any experience with the mexican block? Are these the only differences?

/me Runs outside to check number on block

Nice find! Another example never to take the P.O.'s word on it

Awesome! Good luck with your new project. 289 just a great engine Ford should have kept it around longer!

Always good to hear of a seller's...ahem..."mistake" being to the benefit of the purchaser for a change.
