010 Block: 4 bolt right?

My factory block was only a 2 bolt, but this new block is an 010..so that means it's a 4 bolt right??

Its still a 50/50 chance on being a 2 bolt. All the ones I have seen or ever delt with have been 4 bolt mains besides 1.

Tim,
010.. that either means casting code on the block is 3970010 or that you saw 010 casting code in bellhousing area or in timing chain area, 3970010 blocks were 69-79 and both 2 and 4 bolt, in 69 some were 327

good luck

Like MylilBowTie said, 50/50 chance. I had 6 of those at one time, 3 where 4 bolt, and 3 where 2 bolt. The only way to tell is to pull the pan.
