What's the easiest way to tell if its a 2 or 4 bolt main? (from the outside of course)CE stands for Chevrolet Engine. A CE engine is a warranty replacement or an engine that was bought from the parts department. I think the casting number should be 3969854which is a 69-72 396/402. There is no way to tell the HP rating. What is the casting date? Is it a 2 or 4 bolt main block?

i am about 99.9% sure you are right, i believe thats what i read in my chevy by the numbers book but its been a while and those books are under a lot of stuff (im lazy in other words).Most 4 bolt blocks have the extra threaded plug by the oil filter for running the external oil cooler. I'm not sure what size the plugs are but there should be 2 right above the oil filter on the 4 bolt blocks. Someone correct me if I'm wrong.

Hmmm... I'll have to take another look. There was definitely enough space after the E but I didn't see a number. Of course it was at night with a drop light so I'll take a look see today.Based on this data, looks like there should be another number (year) between CE and the serial number of the engine, 62677.
Above the filter there is one small plug that the oil gauge is tied into and another larger (probably 3/4") threaded plug with the plug in it. Does the sensor plug count as one or would there be 2 of the larger ones in a 4-bolt?Most 4 bolt blocks have the extra threaded plug by the oil filter for running the external oil cooler. I'm not sure what size the plugs are but there should be 2 right above the oil filter on the 4 bolt blocks. Someone correct me if I'm wrong.
