Cam for a 1968 400

Q: Cam for a 1968 400

I’m trying to track down the stock spec’s for the cam in my 1968 Firebird 400 conv. It has no performance upgrades that I am aware of, any help? Lift, duration, lobe sep, etc.

A: Actually the stock cam options for the standard 400 on 1968 birds was the 067(400 std AT and manual), 068(RA-I AT; 400HO manual), 744 (RAI-4speed) and 041 (RA II AT and manual)

Side Notes: 066 was only used on standard 1967 auto 400 firebirds. 400 std autos were ‘upgraded’ to the 067 cam in 1968. Interestingly, the 400 HO auto cars did not receive the cam upgrade (to 068) that the 400 HO manual cars received. Instead the auto 400 HO cars used the stock 067 cam in 1968. Also of interest, the RA I auto cars were ‘downgraded’ to use the 068 cam (vs the hotter 744 cam used on RA I auto birds in 1967).
