the carb i am running is supposed to flow 1000 cfm from a 850 that has been worked on, the headers are 2 inch primaries, george klass custom headers, the car weighs around 3000 lbs., with a c4, 4.30 gear, 60 ft. has been 1.47-1.51, was wondering if a dominator would work, or be too much for it

for 466 cubes, 1000 cfm give or take is plenty in my book. unless your turning 8000+. a dominator could give you some top end but could hurt your low end. my uncles old 472 (7500 shift point) lost two tenths when he went from a true 950cfm to 1050 dom. no matter how he tuned it.
