Default FAST 78mm VS LS6

How does the FAST 78mm manifold compare to the LS6?

I can get a ported FAST 78mm from a friend for $500. It's used, but in good condition. Or I could spend $300-$350 on the LS6. Is it worth it for the fast?

Thanks

It's about the same but the fast is easier to port and I've been told you can convert it to a 90mm. Someone will be able to confirm or deny this but i've been told that a few times.

i believe you only need the top shell to turn the fast into a 90mm, which is sold seperate from the rest of the intake...

Im sick & tired of people giving the impression that the LS6 is superior to the FAST...its probably people who dont own either 1!!! Its better if you want a SLOWER CAR thats about it. The 78mm fast has been proven time & time again to make more Hp & torque over the LS6 so why is this even a discussion; not to mention that all Fast intakes have the ability to be ported. I own a 01' TA that came with the LS6, then i got a 78 mm Fast, now a 90mm Fast when I upgraded to a NW. The 78mm Fast is the winner hands down between the 2, don't listen to ignorance...
