This is a  QUADRAJET 7028210 EE from a 1968 Chevrolet 396 engine .The number on the back left of the base plate is  3327   21 with a sideways T.  The number cast into a circle at the rear of the main body is 7035530.  Had some rough handling and broke the choke pulloff diaphragm. Has a bolt blocking the forward idle bowl vent. Looks complete other than that but has leaf cutter bee stuff in it. Gonna need a rebuild
