Mexican Block

That's a good article.

I read some similar, but less complete, info online as I was choosing a motor for our restoration. I wanted a higher performance motor to install and moth ball the 260. The Mexican block story was intriguing and a quick google search revealed one for sale not to far from home, so I picked it up. I probably overpaid for it at $500 delivered, but I do like the story. A friend has already volunteered to glue corona beer bottle caps to the front block "nubs".

The block was been built and dyno'd just after the last Presidential Election. I Go Pro'd the event and at one point the engine builder and dyno operator were having a chat while I was getting some ear protection. Later, when I watched the video, I got to hear a conversation between the two. The dyno guy was seemingly impressed with the mill and asked the builder about the details. The builder mentioned it was a Mexican block and the dyno guy interrupted him and said "That motor runs great, I sure hope Trump doesn't deport it". I still think it's hilarious.
 
Recently I was looking up info on the Mex 302s, and one source suggested the Iron was of a LESSER quality than US iron.

I have not verified that claim but I have had comments after I have had blocks machined.

Mostly after Alpine blocks have been machined, THEY are not all the same Hardness!

I have been tempted to do my own hardness testing(s)

Dan, was the difference in the rootes blocks between 1494/1592/1725 or difference within same displacements.

Iirc Rootes in some periods added stiffening ribs on the rapier/ alpine blocks over the standard hillman casting but think that was in the 1494s

If you are a forum member and want to add to this thread or any for sale, or wanted ad turned conversation please let me know. I won't give you the hard sell on joining CAT ;) I'll just say post to General Tiger discussion and I'll move it to this thread.
Robert let us know if a Mexican Block or some other reasonable facsimile is obtained, then this whole thread can be moved to a open sub forum .
