Narrative:

First leg of trip. Captain's leg. Aml (maintenance log) review showed aircraft had just had an engine change. On takeoff; noticed odor/ fumes. As climbing out it became stronger. Cabin crew called to say they had odor/ fumes in the cabin. I assumed pilot flying duties while captain coordinated with cabin; operations; and ATC. [ATC was notified of the situation]; crash fire rescue equipment (crash; fire; rescue) notified. As flight progressed; odor/ fumes became less pronounced. Landed on xx; crash fire rescue equipment said no heat signatures; followed us to gate. Normal deplaning. Cause: engine change. Mechanic that met us said maintenance was supposed to have done a high power run up- not sure if it was completed. Suggestions: ensure aircraft is airworthy after major maintenance.
