Bingo, thats why most chevy guys say they don't work, BB mopars have there torque very low in the RPM range, BB chevys don't.
New carbs are useally the way to go, i got very lucky with those holleys i bought, but as long as the throttle shafts aren't shot & theres no water damage, you should be fine with just a kit, normally people don't cut up or modify the 600 1850s, DPers are a different story.
