Is a Mexican Block Worth the Trouble?

[FireSale]

I have the opportunity to pick up a 302 Mexican block for my Super Stock GT Mustang build. I've read that it's stronger than the stock 302 but with two bolt mains, not the BOSS four bolt. Would there be any fit issue with this on the bottom end for a Scat or Eagle crank? I intend to do a complete rebuild and I can sell my current engine outright if I buy a block.

Thanks for your time.

Cranks should drop right in.I'd fill the block to stabilize the cylinder walls and use it.

As much money as it costs to build a SS motor I would use a Boss block. You are probably going to be turning that thing 9,000 rpm. You will be money ahead with the best block you can buy.

Thanks for the quick replies. My car will probably be SSGT/L to M Auto, and I don't think I can get 9000 rpm out of my first racer. BOSS would be the way to go, but they cost a lot. I can get the Mexican for around $300.

You're stepping over dollars to pick up dimes.

I'm going to paint that on my garage wall. Kind of dumb to put $3000 in just heads and a rotating assembly on a stock block.

Ford BOSS or Dart for SS MY stuff is north of 9500 on every pass I wouldn't waste my time or money on a taco block for a stocker much less a SS MOTOR, spend wisely and spend it once we built many nice reliable bracket motors out of Taco blocks I have been doing this a long time and have been using Ford Racing blocks since the A-4 Trans Am blocks became available in 1982 and still do if you want to make power from a little motor you need good ring seal, to get good ring seal you need a good block while better than a stock 289/302 unit, a filled Taco block will still never do the job that a aftermarket FRPP or Dart can..

Thanks for all the replies and suggestions.

I have read that the nickel content is not higher but the casting is a bit thicker and the mains are wider. Stronger than stock but not BOSS strong. It's been mag and pressure tested and the decks checked. I need to see the documents for that as well as photos of the block numbers before I move ahead.

My other option is to build using the current block which overheated and locked up on the way home from the purchase of the car. Read: No option.
