what intake manifold should i get with my procharged 408 well im been waiting for my clutch for over a month now and im getting bored 
i already had my FAST 90/NW setup so thats what im using. and since i havent finished with the dyno im thinking maybe i should change it up now before the tune it done. every talks about loosing low end tq with certain setups. but this in not a daily driver and loosing low end tq for better flow through out the rpms i can take be it i WILL NOT BE ABLE TO PUT ALL the power down to the ground in city streets as it is
thanks steve
just wanted to ***** out some pictures.. like i said bored lol
here it is when car was maybe 2 years old back in 2004

i thought about going back to an LS6 that was my factory manifold. i was thinking about going with the GMPP carb intake. since i already have speedince rails i just need the manifold and intake elbow correct? i want everything to look different, as in when the hood opens people will just go DAMN. plus giving more room to grow. i hate my intercooler piping so i will be redoing that too. and also putting a straight standing radiator.

where do i get this manifold from and can i still use the fuel rails i have with new mounts. and i think the best place to get the elbow was intake elbows or something...

where do you tap into these manifolds for the boost gauge. i dont see any ports anymore
looking at some pictures, looks like i can have the vic jr machined on the top surface to bring the elbow down some to give it a little bit more clearance too
