I thought I read somewhere the mexican blocks had a higher nickel content making them slightly stronger? Maybe mistaken.

all early 302 and 351s had a higher nickel content up until like 74 or 5.

350 and a standard bore, I would buy it. If it was already 30 over I would look elsewhere.

The Mexican block might be worth having if you were using a mechanical roller cam.
Otherwise I'd say no to it.........

Can you expand? Are you only refering to the cost of the special rollers?

Or is there another reason to pass on a mexican block

the strength difference of earlier blocks won't really carry you that far. If you're building a high hp block you'll want to go aftermarket anyway.

it'll cost you $500 at least for retro-fit hydraulic roller lifters. Just for that fact alone i wouldn't get it.

all that said there should be no difference between a block made in mexico and a block made in the usa. If you bought the same size/year block made in the usa it would be the same block.
