JE Pistons - What cylinder size group?

[andrew15]

If I'm using JE Pistons in my 3.0 rebuild, does it matter what cylinder size group I use? Are JE tolerances wider over Mahles so it doesn't matter?

I'm planning on ordering the pistons in the next week and all I've seen so far is one part # for 9.5:1 3.0 - nothing that would indicate different sizes for different cylinder groups.

Thanks,

I don't think they have different size groups. I think the new JE's can be used with the same clearance as the cast Mahle pistons. Are you getting your cylinders replated? If not I'd make sure the bores are round.
