The fit-again striker, the club's top scorer this season, is in contention to return this weekend following a month out with a hamstring injury.
Confidence levels at Palace are high following last Saturday's 1-0 win over Premier League leaders Chelsea and Pulis knows what a boost it is to have Chamakh at his disposal again.
"Chamakh has trained all week with us," confirmed Pulis at his pre-match press briefing.
"He looks ready to go.
"Whether we start him or whether he's involved on the bench, we'll have to wait and see. It's a decision that I'll make closer to the game."
Chamakh was on target in a 2-0 win when the two sides met at Selhurst Park in December and Pulis has been pleased with the Moroccan's form this season.
Pulis added: "He's been outstanding for us.
"For me, he's the player that gives us something a little bit different within the group."
"It will ebb and flow – and that's right through the league," said the Welshman.
"It has been a very exciting season at the top and bottom of the league."
He said: "As soon as we know where we are, what league we are in and what we're doing then we'll sit down and talk to people.
"We'll sit down and talk to Julian along with I think there's six or seven other players who are also out of contract."
