If you go with the tunnel ram your best bet is to buy a direct port kit and drill holes in the manifold (it sucks I know, but that is probably the best way). Either that or run two seperate plate systems activated by 1 switch, but that can be risky. I think the dual 4BBl would be very hard to get the nitrous spread evenly. However your best bet is probably actually to call the companies and see what they suggest. Now that I think of it NOS may make a setup for the tunnel ram intake.
