Is the Z28 LT-1 2 or 4 bolt main block

I see information on the net claiming both. Which one is it. 4 or 2?
thanks

They were all 2, with a few random exceptions from what I've heard. All replacement/service engines were Vette 4 bolt blocks, though, so if you have a crate LT1 like mine, its a 4 bolt.
