Ok, here's the skinny. A friend of mine is running two Mustang Mini-stocks. One has a 2.3 and the other a 2.5. Both engines are cracking the cylinder walls in exactly the same place in each cylinder. One of the motors he had sleeved and the sleeve cracked in the same place! If you're looling down at the top of the block and the water pump is at 12 o'clock the cylinder walls are cracking at approximately 4 o'clock, almost directly towards the head bolt boss. The engines are overheating and he doesn't turn the engines over 7800. Any ideas would be greatly appreciated. Other than this issue his engines are quite strong.

More common when detonation is occuring....Are the cylinder walls scuffing up? Are these small journal blocks? E8 casting number?

How much do you have the head shaved and what cam are you running? Stock carb or 4412, 7448 ect?

Are you cutting the head bolts off so they don't bottom?
