Default Which Intake

I know it has been discussed before but I am wondering which intake I should go with. I am debating on going with the fast 90 or the victor jr. So which is better?

Currently it is a camed bolt on m6 01 LS1. I have jet hots, into an x-pipe for exhaust. Spec 3+ and 12bolt with 4.11 gears. My cam is a custom ground cam. it is very very big. coming in at 246/252, .625/.625 110 LSA. This cam is making strong power all the way to 5900 but then flatlines. I think it is running out of air. A rep at comp used the analogy that it is sucking air through a straw....I have stock heads but have a set of ported and polished LS6 heads ready to go on. I am also changing lifters when I do heads and intake.

Thanks for that link, I have read that thread and guess I need to buy the victor and port it.

looks to me like you have a big cam with stock internals?
i am a vic jr fan which is why i have one , but with your current mods and spinning as high as you might want to would imo be a bad idea. your stock ls6 intake should be fine.
If its FI you are going for the Carb manifold is the way to go as it speads the air out evenly instead of forcing air into the rear cyls like the fast or stock, BUT if you arent going FI i would stick with your ls6 and save your money for internals
If you want to even know about porting a Vic jr. i spent 2k on my porting.

they say go don't bother with the 90mm until you have heads otherwise you won't use them to their potential
