Engine mounting is generally desiged to angle down at 3-4 deg. They are telling you the correct info. Level the frame first. Carb mounting should be level if it has a float. You should then measure a flat spot somewhere on the tranny tail and that will be 3-4 deg. Pinion angle is also important. Angle of trans tail should be same as angle of pinion shaft (parallel). This will make the angle of driveshaft to trans and to pinion the same. That angle should not be over 3 degs either. That can be stretched however. As high as 11 deg. Those guys who put lift kits on their truck have big troubles sometimes if they don't use spacers.
