Re: my new bird
According to my Mitchell Emission control Application guide you need for a '77 pontiac w/a 403(6.5l) pcv,acl,evap,oc,fr,bp/egr,spk, ais.
air injection is california only.
a 400(6.5l) would have pcv, acl, evap, oc, fr, bp/egr, spk, efe
no efe on firebird
hope this helps

Looking at WDDAVIS post, you need AIS. That is Air Injection System(smog pump).
