update, found why i could idle it down but when you gave it gas it would idle back up to 1000. my quadrajet carb base plate throttle shaft is worn and has a huge vacuum leak, you couldn't hear it until you were under the hood and wiggled/moved the throttle. looks like i will be sending my base plate off to cliffs performance to put bushings in for the throttle shaft, thank you guys for yalls help
