LS6 Intake or FAST? 
LS6 Intake or FAST?
uhhh FAST is a better performer hands down than the LS6, but for the money LS6 is the way to go and its not shity by any means in itself ...however if u wanna go and spend almost a 1g on the FAST 90/90 intake..be my guest...i really wouldnt focus on that until ur ready to build a badass motor...hell ive seen tons of H/C LS1's put down 430-460rwhp w/o the FAST...so diff strokes for diff fokes
ls6 is great and all you need for most daily drivers, when you get into bigger cam and heads and cam setups, thats when the fast setup really shows its value, so i mean it kinda depends on your future mods, but for now, you can buy a ls6 intake for 300 and you'll get ur money back when you go to sell it, they hold there value so its really not a lost investment...

For a bolt on car the LS6 is the best bang for the buck. For a mild to medium size cam only car the LS6 is still the best bang for the buck. For larger cams or heads and cam cars the fast 90/90 setup is well worth the extra money spent.

I would not spend the $ on a FAST78, but the FAST 90/90 set up is worth it when you add Heads. I believe the ls6 intake will only flow 280cfm, so once you get heads the intake is limiting. Depends on the lift of your cam & your heads. My ported FAST 78 was Free, but I am going to a Mamo Ported FAST 90/90 set up eventually.
i have H/C with an LS6, i put down 434 SAE. The LS6 intake flows around 280cfm and the heads flow around 310cfm so ill be switching to the ported 90/90 to squeeze all the hp i can out of my setup.
