    What is the difference between a 2843992 and a 2806974 exhaust manifold? Is it just the clock of the flange? Is the angle the same? I have a 2843992 on the 67 GTX and wonder if I get down pipes for a 69 GTX or Roadrunner will they fit.

      Don't know about the angle but the clock of the flange is sure different... So the exhaust will not fit...

      Their page say the head pipe fits 62-79 b-body. That can't be right cause I know the flange is clocked different on the 2 exhaust manifolds I mentioned. Unless the flange is movable on the pipe. Guess I'll call them today. Thanks

      62-79 B-body

      Small block: 273, 318, 340, 360 *

      Big block: 383, 400, 440 *

      Hemis: 426

      The angle is different too. I think if you mate the right pipe up to the correct manifold, it will work on a lot of other B body car years. So I think a 992 manifold with a 68-69 pipe will work on a 67.
