Wow, a 1968. Z 28? And it has a four bolt main?. I don't believe there are any four bolt mains until 1969. Correct me if I'm wrong.
The main caps shown are 4 bolt caps, but I don't see anywhere in the description where it says those are original.
I have heard rumblings over the years that SOME late 68 engines did receive 4 bolt mains, but I have no proof. Jerry M. might know more.
He doesn't really show the bottom of the block, only the caps....Joe
