choosing pistons

[horsepower addiction]

I have coated the pistons with cerakote micro slick to make the piston a little bit tighter in the bore.

knurling seams like it would work. You do it by hand or at a machine shop?

.036 for predator.

I have an extra set of predator gaskets available. I had to get cometic to make me a set of MLX variety... Very expensive.

This is the old way. The problem with this approach is that a lot of cylinders are not able to be honed and almost never match each other. predator Bores can range from 3.697 to 3.704 So when your pistons are ordered to match a particular cylinder bore you are stuck with what you get. If you bore a cylinder then finish hone it to match the piston you have much more control of the tolerances

I'm sorry, struggling to believe a production block has cylinder bores with a variance of SEVEN THOUSANDTHS. Please show an example.
