The 31-year old Hammers captain netted his fifth goal in his past four outings in Saturday's 3-1 victory over Southampton in front of England assistant Ray Lewington who was present at Upton Park.
Nolan has been one of the form midfielders in the Premier League recently but Allardyce suggests perhaps his best Three Lions opportunity has passed him by.
"He has had a lot of times that he has knocked on the door and I don't think that's going to make much difference for him now," said Allardyce.
"It would be nice if he did, but it is just about Kevin continuing where he is now.
"He is in his thirties now so he has got to continue his career as long as he possible can by doing what he has always done and that is score goals.
"Apart from a short spell out in the Championship with Newcastle, he has scored goals every single season he has played at a very, very high level for a midfield player.
"There are very, very few players better than him at scoring goals from midfield."
Nolan, who joined the Hammers from Newcastle in 2011, has never played for the Three Lions during his 14-year professional career.
