Please what does the price quote for the various repairs in the categories entails?

I just bought a new engine for my Pontiac Montana but the sound is poor as if the tappet is bad, we removed those from the old engine and replace, still making noise. I need a good mechanic to look into it. I need a cool engine sound.
