    I don't know if you can put too much confidence in the intake manifold for the engine size. If you go back in this forum to a post called "Information needed on 1966 Tbird" by Joeo 51 on Nov 19, you will find in the replies a web site, called "erareplicas.com, which should give you the information you need.
  3. Thanks I will go there
