Engine replacement
 

My 07 xc70 needs an engine it is the 2.5 . What other year/ engines will work? And app how many hours labor for ancient hot toddler?

check the nose of the engine or the build plate to find your engine code (ie B5254T2) then go to the Volvo Modular Engine wiki page to see what other models use that engine.

Are you looking for the hours labor to swap the engine to size the job for yourself or for a shop to do the work? Most shops use a quote tool to estimate the job so you can call around for estimates. The hours shouldn't vary too much.
