You are going to have a very dry roast!!!!
Depending on the type of meat 20/30 mins per pound + 30mins. Id cook a 4.23 lb roast for about 2 hours 30 minutes at 180 F, as I like my meat well done.If cooking Pork make sure its not 'bloody'.
The best thing for you to do is to pick up a meat thermometer. If possible, try it out once or twice before a critical meal to make sure you know how to read it accurately.
you should roast a piece of beef at the temp of 160 deegrees This should read "TO the temp of 160 degrees, internal temp" (for medium doneness) If you roast it AT the temp of 160, it will probably spoil (or wind up full of bacteria) before it ever reaches doneness. Medium rare would be done at an internal temp of 145. Your oven temp should be at least 250 to 350 degrees depending on the size of the roast, the vessel that it is being roast in, covered or uncovered, & desired browness on the outside.
My rotisserie book states 18 minutes a lb for rare, 19 for medium and 20 for well. But I check with a meat thermometer at the rare mark and take it out to sit for 10 minutes.

Roasting times for beefPreheat your oven to 160°C (325°F) and use these cooking times to prepare a roast that's moist, tender and delicious. Your roast should be covered with foil for the first half of the roasting time to prevent drying the outer layer.3 to 5lb Joint 1½ to 2 hours5 to 7 lb Joint 2 to 2½ hours7 to 10lb Joint 2½ to 3 hoursThe beef can be taken out sooner if you prefer rare (bloody) meat.Tips for a better roast. For extra flavour you can add optional vegetables such as carrots, parsnips, onions and celery to your roasting pan, and roast the meat 'on a bed' of vegetables. The vegetables also help to keep the roast off the bottom of the roasting pan so it doesn't 'stew' in its own juices.
You should prepare a top of the round roast by removing it from the refrigerator one hour before cooking. Pat the roast dry with kitchen paper, massage some cooking oil all over and season it with garlic salt, salt and pepper. Cook at 325 degrees Fahrenheit or 160 degrees Celsius for about 2 and a half hours.
