I ordered some sealed power .010 oversize main bearings for my 1967 250 L6. They have a hole for the oil hole, however there slotted bearings and the slot fits over the oil hole as slotted bearings do. I know this bearing kit is for my engine as the cap bearings fit perfect, and the thrust bearing has an oil hole that lines up perfect, and there are seven bearings total, equaling the seven bolt main. So has anyone used the slotted bearings with success, would I be safe using these?
