Recommendations for tools for measuring engine clearances

I'd like to get a dial bore gauge and caliper so I can measure bearing clearances and cylinder bores. Looking for recommendations for each that won't break the bank but still do a good job.

Those are just references measurements so repeatability is the most important thing. You can get away with cheap ones but if you might use them for other stuff, Starrett, [email protected] and Mitutoyo are good ones for general purpose.

I've always used micrometers not calipers. Maybe I'm wrong, but my understanding is that the accuracy of calipers is only .001

Yes - 2" minimum. Didn't work on my big build though - 1.2L Austin Healey - lol.

You're not wrong. As a machinst, I only trust calipers up to .002/.003. Anything less, O.D. or I.D. mics only.
