For an 8lb turkey crown, you should roast it at gas mark 4, which is equivalent to 350°F (175°C). Cooking times may vary, but a general guideline is about 18-20 minutes per pound, so plan for approximately 2.5 to 3 hours of cooking time. Always ensure the internal temperature reaches at least 165°F (74°C) for safe consumption. Let the turkey rest for at least 20 minutes before carving.
20 mins per kilo an extra 70mins if under crown is under 4 kilo 90mins if over 4 kilo
between gas mark 3 and 4.
Gas mark 4.
gas mark 4
The equivalent gas mark would be 4, although all ovens vary so check the documentation that came with your own to be certain.
4-5 gas Mark
It would take about five hours to cook a 13 pound turkey on normal setting. However if there is time it is worth cooking the turkey on a far lower setting such as gas mark 2 and doing it fr 12 hours to get a more succulent bird.

To convert 165°F to gas mark, it corresponds to approximately gas mark 3. Gas mark 3 typically ranges from 325°F to 350°F. Therefore, 165°F is actually lower than gas mark 3; it would be closer to gas mark 1 or 2.
300 degrees Fahrenheit is equivalent to gas mark 2.
I'm guessing you mean 350F, which is gas mark 4.
