Q: estimated, this product will be compatible with a mercruiser 4.3 engine series engine of007457?

I used one on a 93 GM -4.3 from a van by just removing the original intake and purchasing a new Edelbrock intake made for that engine . I used it in my street rod for a few years . Check with the Edelbrock company for more information .

Q: Can you tell me what all the vacuum ports are for? It has more than a normal Qjet

Each car has a specific set of emission related vac requirements so best to refer to a manual

Q: Is there any kind of tuning instructions?

No instructions but not that hard to tune. There are three screws on the brown round thing that you loosen and then adjust to tune.

Q: Where are the directions? It has different jets and no directions on what the different ones are for or how to change

Take the top off the carburetor jets located inside. Unless you’re building a hot rod there is no need to change the jets. I put mine on a 454 motor in my RV and made a small adjustment in front of carburetor. My RV is 36 feet long.
