Finn made his debut on the winter tour of Bangladesh
England seamer Steve Finn believes his team have a total with which to control the first Test after Bangladesh closed day two 333 behind at 172-2.
"We can say we could have got more runs but 505 is plenty," said the 21-year-old, who took 1-39 on home Test debut.
"The wicket seems to have slowed down a bit, there's not too much spin for Graeme Swann but as the game wears on it will start doing a bit more.
"There's been a bit of variable bounce and we could potentially exploit that."
Day three could be one of frustration with the forecast for rain, though the Middlesex seamer added: "We can't look to the weather because 90% of the time they get it wrong!"
Bangladesh frustrated England with some powerful batting as left-handers Tamim Iqbal and Junaid Siddique struck 55 and an unbeaten 53 respectively.
"They've got people who can really adapt to the situation in the game and it's important we come out and try and tie an end up and take wickets," Finn said.
Recalling his first Test wicket on his home ground he said: "It kicked off not that short a length, it was nice to get a bit of bounce and I think it has been bouncing more from the Pavilion End but it's important we try and dry them up for runs.
"There was a group of wickets from me and the bowler at the other end and I think building pressure is going to be a big thing for us."
Finn favours the Pavilion End at Lord's but was asked to switch and said: "That has quadrupled my overs tally from the far end this year but I have to be flexible for the captain and if he wants me to bowl from the Nursery End then I have to.
"It's up to Straussy [captain Andrew Strauss] to bowl me where he thinks and up to me to be adaptable and be put into any situation in the game and important I can bowl from any end with any state of the ball."
Regarding Tamim he said: "He's a challenge to bowl at, it's something we don't experience too much over here, he played some very good shots.
"If we bowl dot balls at him he's going to try and play a shot and that's what is going to get him out.
"I think it's important that when we bowl at him in the second innings that we don't let them get off to the start they did today."
