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

$ per $ the ls6 wins.
i think i read that the fast 78 makes a lil more hp/tq

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...
