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.

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.

I agree a Boss block would be the way to go if you can afford it.The stock block deal has been done before too.

If you have the money get the boss block it's alot better than the stock block..but I know a few SBF guys that are running the stock block with no issues in SS.. I would def put hard block in it. I have a Mexican block in my mustang and has run some 10.30s...with a stickshift at 7400rpms..

I don't know about filling a Ford block, but I've filled three GM 283, and 327, and 350 blocks in my life. I would NEVER fill a block. Every time we've done it, when you get ready to re-hone, the chatter from the stones going down in an oblong bore, is deafening. They NEVER stay round. On the other hand, when not using filler, the block was WAY straighter. And yes, we use a plate.

Randy,
Curious as to what you filled the block with ? I had the same experience years ago with a block I did for a customer that he had filled. He used one brand of filler that I had never used and his block did move around a lot on the first freshen-up and a little bit the second time.

I have always used Hard Block and have never had it move around ?
