Appearently my block was zero decked to my pistons which had a 1.130 compression distance, my new pistons have a 1.125 compression distance, does this make my new pistons .005 further down the hole or higher up near the cylinder head?

thanks! also, quick question when I am figuring out my CR, it asks for piston to deck clearance, I used to put a zero in it, but now should I make it a .005 or -.005?

Thanks guys !

 

the piston is going to be further down.. and for the compression thing, just do two calculations.. one with -0.005 and one with +0.005 and take the lower compression ratio.. its not that hard to put a minus sign in or take it away.. not tryin to rag on you but next time just try it.. it can only be one of the two..

 

Thanks I understand, I really needed to know if it would be farther down or farther up, I could have figured out the second part.

 

Your new pistons will give you .005 greater clearance.

I like to use this calculator

It's self explanatory.
