| Re: Split Block ????
Your basic, runof-the-mill 5.0 block is prone to cracking at the main webs as shown in the above pictures when:
a) it is over-revved, and
b) when it puts out more than 500 hp.
The 2-bolt production blocks are great if the revs are kept low and if you don't try to squeeze too much power out of them. Still, there are a number of bad apples out there due to core shift in the casting process. I think the Dart aluminum block would be perfect for a GT40.
Oh yeah, regarding nickel content, the Ford Racing catalog states that the Mexican blocks had the same nickel content as the US production blocks. Just a rumor. As Built2rev said, though, they are a little beefier. |
