Firebird 400 questions
I have a friend looking at what may be a 67 400. What separates the car from a standard car?

Obviously the 1967 400 engine, correct engine code, "067" heads, correct number Q-jet, etc.. 1967 will not have the vehicle VIN number on the engine block as that was started in 1968. So, you will want to use casting date codes found on the heads and block and should be very close in date to the build date of the car. The 400/326HO had 2 radius rods at the rear axle while non-400 cars only had 1. The radius rods go from the axle to the body - sorta like a traction bar. This will be in addition to the rear leaf springs. I read another article that says the automatics has 2 rods and the manual cars only 1. |

The "traction bars" of the 67s were by drivetrain - depending on performance engine, manual trans and axle ratio. I believe it's charted out in the Service Manual, which is a supplement for Firebird. Even the Sprint six and the 326 HO had 2 bars with certain trans and ratio configurations.

'67's are easy to identify a 400 model. They will have 3f on the data plate. Only year they did it that way.

Thanks a lot for the replies guys. Though I have a one owner original 69 400 I’m not too familiar with the 67’s. The car does have the two traction bars, the 400 hood and the close out plates in front of the core support. Going by Camaro specs, the 400 hood is original also.

Thank you Mike, that may be the most original 69 400. One thing I found was a restrictor in the return fuel line which I replaced when restoring it, puzzeling. Got a picture with the original owner with it after it was finished.

67 automatics only had a single radius rod, no matter what motor.

I found the supplement manual online and captured a screenshot of the radius rod application chart.
