Rochester TBI throttle body, harness, conversion plate
I believe the TBI units are a special pattern
OP--Holley used to make a 2bbl TBI "Pro-jection" I don't know if the Holley bolt up is same as Rochester or not. So the Holley adapter would be to mount a 2bbl Holley TBI unit on either a 2 or 4bbl "standard" American V8 setup
