My block is about to go out to 1380 to suit a set of pistons I have.
These pistons were run in on another motor then ripped out a couple of hundred kms later.

The machine shop wants to know what piston to bore clearance they should use in the new work.

Advice?
Whats normal?
2 thou?

Cheers

Forged or cast?

you will need to find out & adhere to the manufacturers specs for clearance
