I am going to be zero decking my block...I think. Here are my questions:

Do I need to mock up the engine before getting it decked to do an actual measurement before telling the machine shop how much to remove or is it "close enough" to do a stack up of the parts advertised dimensions and go with that? For instance, stack adds up to 9.001.....just tell them to take it to 9.001.

Can I tell the machine shop to just take the deck to 9 inches or do I have to tell them how much material to remove? (I think deck height is measured from the center of the crank and wasn't sure how they get that measurement if hand them a bare block?)

What is a ball park figure for the cost of decking the block?

I am sure these are easy questions as this is the first time having any machine work done to a block.


The simple answer is no you don't need to mock up the assembly to determine
your desired deck height. Good shops have centering fixtures such as a BHU Block-Tru that is indexed on both cam and main bores and can be used to establish a desired deck height while assuring that the decks are square and 90 degrees to each other.
