So i got a new engine for my 2003 Mazda p5. When I bought the engine, I put forth as much effort as I could to make sure it was for a manual transmission. I have a manual, but they sent me an automatic. How do I convert my block to fit my manual transmission? Everything fits down to the flywheel, including clutch assembly. Except my clock pattern doesn't match. It looks as though I can take my short block off my old engine and swap it to my new one? Am I correct or in over my head?
