Vintage Thunderbird Club International

No thanks.

"If your engine is stock, the rocker arms are in good shape, and you have no trouble adjusting them, I wouldn't be too concerned about the ratio".

I would be, due to the unbalanced 7+% difference in flow area between the two heads.

That looks exactly like the vinyl top that was on my 55 when I bought it in 1965.
It has never bothered me that it wasn't original.

Thanks

"The chrome headlight eyebrows were NEVER an option on the Thunderbird".

This memory is from back in the day. I believe the first 14 Thunderbirds had them.

Paul, do you have contact information for Williamson?

I think I may have more confidence in my mechanical ability than you do. :-) Been working on automobiles, airplanes, and boats for over sixty years now.

"TCI should have an AOD shift kit that will allow holding 2nd without having to manually shift back into low". Thanks for the info. What's the issue with shifting back into Low? I got used to doing that in 1965. Never saw a problem with it. I'm comfortable with modifying mechanical devices...

55blacktie, could you say more about the AOD valve body mod?

For me, it was very desirable with my 55 Fordomatic. It allowed the two speed T-Bird selector to access all three gears at will.

I do not know if it will work with a C4.
