I want to trim out about 80' block wall with baseboard at the top where it
meets a drywall ceiling. What's the best/easy way to do it without
cracking/splitting out the block? TIA

I'm leaning toward adhesive with a couple of cut nails in the mortar to
anchor it while the adhesive drys. I wonder if roofing cement or a
flooring cement would work better; e.g. hold the baseboard without it
slipping down the wall?

If duct tape is out of the question, think combination Liquid Nails and
contact cement.
I just tried a can of "3M Hi-Strength 90 Spray Adhesive." That stuff will
glue an ice-cube to an after-taco belch.

A few 1x3 springboards would do the trick. Just cut the 1x3s an inch
long and wedge them into place under the molding at suitable
intervals. That'll hold it while the adhesive sets.
