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

Just drill and tap the holes to the preferred bolt pattern. They work very nice.

This is a a Mopar Mid Rise Dual Plane TBI intake manifold drilled for the Edelbrock 4 bbl adapter. For those that don't want to deal with the throttle body electronics.
