resurrecting an old thread.

I measured a plain bearing journal on an 80K miles 350 A engine as 46.28 , and the standard size is 46.355?

Mdina part lists 25.03.20 shell mains brg oversize i/d 45.9mm
but that's -0,45 (approx)
Is there no longer -0.2 option? part number 25.03.20 is supposed to be -0.2mm
And this is the complete assembly?
Thanks
Mark

hello Mark,

When I did my crank only the second undersize was available.

Not wishing to be pedantic, but don't you mean undersize?

Thanks Mike.
Quality? Good, OK or bad?
Are they split like the original?
