Clark came off the bench to net a dramatic late winner in the 4-3 win over SPFL League One rivals Brechin City at Glebe Park.
The striker's goal capped a stunning comeback by Ally McCoist's side and kept alive their hopes of winning all their league games in the 2013/14 campaign.
The Gers, who moved 10 points clear of nearest rivals Stenhousmuir, have now won their opening nine matches.
But Clark, who is now hoping to get the nod to start against East Fife in Methil this weekend, reckons the Brechin match was a reminder how tough maintaining their run will be.
The 22-year-old won the Second Division with Queen of the South last season and knows how difficult games on the road against third tier opposition can be.
He said: "Places like Brechin are really hard to go to and win games. You saw just how difficult it can be in the first half of the win on Saturday when we fell 3-1 behind.
"Fair play to Brechin. They did really well, they deserved to score their goals and to take the lead as they did.
"The gaffer had a few harsh words for us at half-time and fortunately we went out in the second half and managed to win it. But it was close."
Clark added: "I have played at this level before and I know exactly what to expect. Teams always give 100% and they have a lot of ability as well.
"Brechin were excellent in the first half and we will come up against more teams this season who will play exactly like that.
"Every team that plays Rangers ups their game when we visit and we can't afford to perform at any less than our best.
"It is down to us to make sure we match the commitment the teams that we play against show."
Clark has featured sporadically for the Rangers first team since joining from Queens on a free transfer during the summer.
But he is hoping the impact he had against Brechin will force him into McCoist's starting line-up for the league game against East Fife at New Bayview.
He said: "I am like any footballer. I want to be involved in matches. I want to start games.
"Hopefully I have given the manager something to think about with my goal at the weekend.
"There are a lot of good strikers at the club so we will have to wait and see what happens. But hopefully scoring the winner helps my cause.
"I really enjoyed being part of the team at the weekend and was pleased that I could help us get a victory in a difficult away game.
"I will keep working hard in training and hope the manager picks me."
