Re: Need a couple more- Lookin for NHRA Stock Class Factors
eg 1967:
Was the "325hp" Firebird RA1 up-rated to the "360hp" Tempest RA1 rating? (which I assume was left as-is at 360)? Were both the stick and auto cam engines left with the same rating? Yes.
1968:
So, was the "335hp" Firebird RA1 up-rated to the "360hp" Tempest RA1 rating (which I assume was left as-is at 360)? Were both the stick and auto cam engines left with the same rating? Yes and yes.
1968-70
Was the base "330hp" Firebird up-rated to the base "350hp" Tempest rating? No. 1968 Firebird was left at 330. 1969 and 1970 Firebirds were 350.
1969:
Was the "335hp" Firebird RA3 up-rated to the "366hp" Tempest RA3 rating? Yes.
1970:
Was the "345hp" Firebird RA3 up-rated to the "366hp" Tempest RA3 rating? 345hp Firebird and the 366hp Tempest were both at 366. The 370hp RA IV engines in 1969 and 1970 were at 380.
