Casting number

cuda67 said

I do not know anything about casting numbers, my bad. I am looking at a 360 with the following cast #, 4006830-360-2. I know it tells me it is a 360 but what else does it indicate? I assume it tells the year. But I don't know? Any help would be appreciated. They want 500 for it complete. Just found it on, CL in Florida. Waiting for a reply on the miles. It says it is a 78 with about 400 hp.

A quick google search of the first part of the casting number pulls up a few links that indicate that this block casting was a 5.9 360 V8 4.00" bore block produced from 1971-1989. I don't believe the date is in the casting number, but there should be a date code stamp on the block.

As to whether it is worth $500 is dependent on it's condition and compliment - what does it come with? heads? intake? what vehicle did it come out of?
