| Re: Split Block ????
CraigW,
The cracks running down the webs from the main stud hole are pretty typical. It did get me to thinking though; was the guy running main STUDS? If the studs are bottomed out when they are installed, they can put a huge amount of stress on the webs as the engine heats up and things start expanding.
I am glad to hear that nothing untoward happened to anyone or the car. It is great that he can salvage most (if not all) of his new parts. In order of preference, suggest he look at the Dart Iron Eagle (4 bolt all mains), Dart Sportsman (4 bolt 2-4, 2 bolt 1 & 5) and the Ford Racing R302 (4 bolt 2-4, 2 bolt 1 & 5). The Dart's webs are beefier than Fords. The cylinders are truer as well; this means you can go to 4.185" bore without ultrasound with the Dart blocks. The max on the R302 is 4.125 I believe. Dart has true priority oiling for the mains and a number of other really nice features. If you or he would like more info on the Dart blocks, let me know. I have info on the 8.2", 8.7", 9.2" and 9.5" deck height blocks. You can also order with 4.000 or 4.125 rough bore. (They will hone to these numbers, but they do have to be honed. While not finished blocks, they are said to be more finished than the R302.)
