Anyone running these yet ? http://shop.virginiaspeed.com/produc...&categoryId=64 They look like a great option for those with a 4.00 bore . I'd really like to see how the 2 port sizes compare to each other .

That is great flow for the port & valve size . I can't imagine the cross section being very large . Your build sounds awesome ! Depending on your other components I can see your engine capable 700+ . I'm only building an LS2 based 402 that will live on the street . If you don't mind how much do you have in those ? It would be great to have them setup for hyd. cam & assembled for under $3k . WKMCD , Shawn @ Va. Speed ported your LS3 FAST intake ? What rpm are you making peak hp & torque ? 577 is pretty good with a small cam .

The heads really perform ! I like WKMCD's torque . 850 running alcohol from 408 cubes is bad ***, anything over 2hp per ci is awesome . I was looking @ the smaller 235cc port as I would not turn too much rpm . I'd really like to spin it but the t56 just doesn't like shifting @ 7500 .

I like the option to expand in the future and the 250's don't have a huge intake valve either . What rpm was that 800 @ ? I want an intake that won't be a bitch to install . I don't mind cutting but I'd like to drive this pretty regularly . I see a stock LS7 intake can be bought for a few hundred . It seems as if I can run these for about $4k .
