81 Magnum factory 360.
I know because the engine is not EPA approved, can't bring the car over the border.
If the car is 25 years old or older, it is EXEMPT from EPA and DOT requirements. It is however NOT exempt from individual STATE requirements. California would be an example of a state where you'd have a terrible time trying to get the car titled and registered and smog checked. New Mexico, Arizona, Massachusetts, New York would be a few more states that make it REALLY tough to get imported cars road legal.
So starting in January, everything 1994 and older is fair game.
So that includes every F/M vehicle down there, all the stick shift Chevy Celebrities, all the Rambler/AMC/VAM craziness, and the Fairmonts. So many Fairmonts. Oh, and Malibus. Remember the Iraqi Taxis? That's something you'll see down there too, 78-83 Malibu coupes and sedans and wagons and pretty much every single one with a 305/350 combo or a 305 with a 3-speed manual.
Something else you'll learn about 70s-80s-90s Mexican market vehicles. To be sold in Mexico, they had to be built in Mexico with an engine made in Mexico. You will find Slant Six and 360 powered Chryslers but NEVER a 318 unless it was imported from the USA. You will find V6 powered Chevy Celebrities but never a 4-cylinder, because those Iron Dukes were all made in Canada.
20.6 pesos to the dollar exchange right now. So if you see a car listed on a Mexican website for $50,000? That's a $2500 car. So look at the price, cut it in half, take off a zero. Kinda like we OUGHT to be able to do with all the $10,000USD Fifth Avenues here in the States.
