The packers that i get as corned beef weight between 11 & 14 pounds, they have been "corned" for 21 days by the butcher, the thickness ranges from 2" - 3" depending ont he cut, Pastrami is just corned beef seasoned and smoked, i use a dry rub of ground corriander seed and black pepper corns rubbed all over, i smoke it at 235 for 7-8 hours turning it once or twice, temp varies between 165-180, pull from smoker, wrap in foil let sit for two hours, then slice. good luck
