New member with a 318!!

I dont mind upgrading the valve springs while Im in there since Im gonna have them off for valve seals anyways..... So if I buy a cam/lifter/spring pkg what am I looking at? I read some old posts on here where there was alot of talk about mopar perf. camshafts with springs....

How hard would it be to carry my stock little 318 longblock into the low 13's with say a set of 3.55's in the rear?
