Most excellent build Mark, I know how you feel about driving it,
you would be amazed at what people will let you do for an 8x10
glossy of their car especially at a race track it is a great thing
to be the photog sometimes!
Amt's 66' Tbird would be more accurate and for an engine you
could use the 390 Tbird or the 429 from Revell's 1970 Torino
also the auto trans from the 66 Fairlane could be used although
in reality it wouldn't bolt up to the 429 depends on how anal you are
The main thing is have fun!
I am planning on being there also as I live on the west side of the state
and had a great time last year they had almost double the model turnout
than they thought, at least thats what I heard.
