our 66 was a 428 Q car has a 390 in it now. Tag facing car right side intake manifold reads right to left 390 70 12 top set of # bottom set of # read 9 K 311. Not sure but I think it came out of a 69 Mercury .I have been looking my self but not really to sure about it. Any help with this would greatly appreciated. Thanks

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.
Cheers
