@bobevansclassics: THE LEGEND OF THE “MEXICAN BLOCK” 🇲🇽 Back in the day, Ford produced certain 302 small-block engines in Mexico, and many reportedly found their way into American cars as replacement or service engines. These blocks became legendary among Ford enthusiasts because they featured heavier main-bearing caps—similar in design to the respected 289 Hi-Po caps—and were believed to be stronger than the average production 302 block. You’ll also hear stories that they were cast with thicker cylinder walls or a higher nickel content. Those claims have never been consistently proven, but they helped create the Mexican block’s almost mythical reputation. Authentic examples are generally identified by “HECHO EN MEXICO” cast into the block, along with distinctive casting marks. Is the Mexican 302 truly one of Ford’s strongest factory small-blocks—or has the legend become bigger than the engine itself? 👇 Ford guys, tell us what you know about the Mexican block. #Ford302 #FordSmallBlock #MexicanBlock #FordMustang #ClassicFord #EngineHistory #ClassicCars #BobEvansClassics
I was always told the Mexican block was better that it had a higher nickel content

The phrase "Ford warranty blocks from Mexico in the 60s" refers to a legendary line of heavy-duty 302 cubic-inch small-block V8 engine blocks cast at Ford’s Cuautitlán Assembly plant in Mexico starting in 1968. They earned the nickname "warranty blocks" or "service blocks" because a vast number of them were imported into the United States to be used as over-the-counter service replacements or factory warranty replacements for blown engines.Why They Are FamousAmong hot-rodders and Ford performance enthusiasts, the Mexican 302 block is highly desirable and considered one of the strongest factory production small-blocks ever made (outside of the specialized Boss 302).

Ford had a plant in Mexico that made a hipo style engine block. Commonly seen in warranty and service motors never used on us production from the factory

here's the correct answer, the plant was built in 64, they built truck motors and handled some US shortages. the truck motors had beefier mains and thicker webbing etc, which means they could in fact handle more overbore for the safe temperature and hold together better and longer at higher rpms.

The Mexican blocks i always seen had a nipple in the front of the block easy to see, I ran a couple of them at 60 over and both ran cool even in 100 degree traffic
