engine progress/new ?

[mudchucker]

ok guys, the block is at the shop and it is needing a fair amount of work. so here is what i am going to have once back. polished crank, .030 over, new rods, new pistons, rousch 180 iron heads, roller rockers. i am going with a comp cam, but the numbers have been taken from my brain violently. i do know that it is the one slightly more aggresive than the ford E-cam.
here are my questions: i am going to be running a cobra intake and 70mm throttle body. this will be speed density (i hope) because that is what it is now. will i need to run larger injectors? how bout the ecm, what needs to happen there? and how about the fuel pump?

any help in the right direction is appreciated!
