The 1850 carbs are almost impossible to tune unless you're willing to spend a bunch of time with drills and epoxy.
Andy, not to start a debate, but i've used 1850s on 2 of my builds, both being -2 & -3s, one being my old Duster with the 451, & the other on a basically mild low comp. 440 in my D-100, on both accations it wasn't hard dialing in those carbs, once they were tinkered a bit all was spot on & never gave me any fits, even on the street, The duster still has this set-up after 5yrs. & the other owner loves them, & he's has never had to tweek them any more, not saying the eddys won't work good also, i'm sure they will.
That's whats funny about your response, and your opinion. Those are not very good carbs for that combo. Most of us that replied, HAVE, tried more than one combination on a tunnel ram. Call a custom carb shop, and do it right, and do it once. Get the right carbs already set up on a dyno and calibrated to your fuel flow needs.
The newer carbs will also have a lot more range of adjustments with replaceable air bleeds and boosters which can be tailored to your specific application. My personal preference is to get annular carbs anytime they are available for my applications. They are phenominally responsive, and help with milder combinations.
Frustration in the set-up and tuning of those is not worth it. Tunnel ram carbs take a lot of time to sort out, and if you pick the wrong carbs to start with, lots of time followed by frustration. Box stock carbs rarely work on Mopars. The only one I have ever liked out of the box that was right on for a mopar is the 8896 Holley dominator on a mild race prepped 440 or 451 with around a 590 cam.
