Press Fit

[440 Mike]

1.094 wrist pin. What should the connecting rod small end measure for a press fit application?

1.084-1.087

"...Always refer to the rod and piston maker’s specifications. But generally, a press-fit pin requires a .0005- to .0009-in. interference fit between the wrist pin and rod small end..."

Thanks for the replies. The small ends are measuring at 1.086, so should be good. This is a a future 440 budget build.
