Cross Ram tuning, where to start?

[68454RS]

I picked up this old Edelbrock X-C8 crossram and i'm looking for advice on carbs. Holley recommends the 450 tunnel ram carbs but others have said to go with the 600's. Any of y'all ever set one up and get it tuned good?
It's going on a mild SBC 383 stroker, 401hp @ 5200 rpm 437tq @ 4200 rpm 5500 rpm rev limiter

The manifolds look cool, but were not the best performing setups. Seemed to work good at WOT. I would be thinking a pair of 390's or 450's max on a mild small block that's a street car.

Yeah, That's about all i've heard is that these are not good for performance. I am going for the cool factor but still need to be driveable.

pick whatever carbs you want, and a vacuum gauge and get to tunin..

cant be any harder than a 'normal' tunnel ram or any dual carb intake really.

you might have to get one of those cones that go over each carb so you can get them balanced

but any tunnel ram, or dual carb rig ive had, i just tweak each carb a little by little and then readjust idle on each.

its really not that hard, and even easier if you have a nice smooth not lumpy cam
