This is a real deal 1966 427 4 bolt main engine block.  This was recently found at the estate of an old hot rodder along with many other cool parts from his personal stash.
I took the block to the local machine shop to be cleaned, measured and magnafluxed for cracks. There are no cracks. The cylinders measure .060 overbore or 4.31 inches. The block has no sleeve or repairs. The cylinders have no ridge at the tops of the cylinders and do have significant pitting. Due to the pitting, I think the best plan would be to sleeve it back to standard bore for correctness. That said, these blocks are known for taking a huge overbore and boring may be an option. There are also multiple head bolt threads that have professionally installed helicoils.. The externals of this block are nice with clear casting numbers. These are scatter areas of pitting on the casting including the rear of the block and the stamp pad area. This block will need full machine work but have never been blown up for cracked and will be an awesome piece when finshed. These original 1966 427 blocks are becoming very hard to find. They were quite rare when new and are even harder to find today. Don't miss this original 1966 427 Big Block Chevy block as a great price.
Please don't let the price of this block fool you. There are others listed on Ebay for twice and three times what I have this block priced at. This is a nice block, not junk. I am simply being realistic with pricing so this block can end up between the fenderwells of a car rather than on a stand in my shop.
