Mine ended up having the small hole so I guess it must be a 2 bolt main block. It does have the 2 step oil pan on it. Would the 325hp motor have a windage tray! I will double check it when I get time. I have been looking for a April or May 440 4 bolt block for my 68 L78 nova. The one I just got is a E-18-8 block.The motor I have in the nova now is a 2 bolt main out of a 68 4 speed 350hp chevelle. I want to build a correct L78 motor for my nova in the future. If this block I have would have worked then I was going to use it. I thought the only difference might be the main caps. So I guess the search continues and the motor will most likely go into the 67 chevelle.
