What does it take to be a lineman?

so im trying out for powder puff at my high school. im not sure how many people theyre gonna cut but i figure if anything id be a good contender for a lineman. im not that fast but according to my football friends im "beastie". haha im not like a tomboy but i ges im kinda big like tall and a bit heavy. so what exactly does it take to be a lineman and could i have a good chance. on the 40 yard dash i got like 7 secs and the agility test 5 secs. and then we did routes and i caught most of them.
