I have a 2000 silverado ext cab currently has a 5.3 which is coming out soon.

my build consists of
LS1 completely refreshed, honed, bearings, rings etc etc everythign new,
will be getting some 243s doing a port and polish on them.
custom grind cam 6xx/6xx on a 110 lsa around that area.
3800 stall
adn 410 gears.

my question is what intake do i go with?
i was thinking of getting the nnbs intake, but then the holley hi ram intake interest me too..

I have a FAST 90 on my LS1. Makes good power if you're after higher RPM HP.
