I really don't know what the all-time documented record length is, but here is some natural history info that I would have to agree with. It's pretty much what you stated.
the weight could vary quite a bit I guess too depending on the captive feeding schedule of any particular specimen.

Adult size....

African House Snakes are highly sexually dimorphic in size. Females attain larger adult size than males. Adult male L. fuliginosus rarely exceed 3 feet in length, while adult females can exceed 5 feet. On average, an adult male captive born and raised house snake is between 24 and 30 inches (60-75 cm) while females typically range from 3-4 feet (90-120 cm).

Although they can attain almost 5 feet in length, House Snakes are slender snakes. A large heavy bodied female would rarely exceed 500 grams whereas the smaller males rarely exceed 200 grams.
