cam for my 440 build

[Romero14]

I am needing some advice on a cam for my 440 build. The car will solely be used on the street and will have power brakes. I am not sure on intake and tire height yet, it will have 3.55 gears and a 5 spd Tremec TKX. I am hoping to get something a little hotter than stock but not too hot to where I lose vacuum. Here are a few that I am looking at.. feel free to give any feedback and other recommendations. The first is a comp cam xtreme energy and the other two are Howards.

this is what I am running with my 440 auto, also with 3.55 gear:
   • Comp Cam 21-404-4 Hydraulic Flat Tappet
      ○ Grind: CRB 265DEH-10
      ○ Intake: Lift .442, Dur 214 @.050
      ○ Exhaust: Lift .482, Dur 229 @ .050
It is street only and I love the performance (and sound). It did not give me enough vacuum for brake booster so I got a Hydro-Boost, which is amazing.

I was trying to avoid a booster if possible.

Take a look at a lunati 703LK.
Works great in my 440 with power brakes
