You´re correct, Carter never made RamAir units.

#37489 between plates indicates an aftermarket Carter Q-jet replacement unit.

It, may have started it´s life as a Carter 4987S or 4988S.

I have a NOS 4887S with cast "3" beneith fuel inlet and #37478 stamped between plates.

These units also have the early (1969-70) POE-system, two holes in the back wall of choke housing, under choke blade, serving dual purpose as choke enrichment/high speed enrichment and secondary main well airbleeds.

RA units do not have the POE system.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
