Hi All,
hope you can help with our query. We have just finished preparing a 1970 Camaro with an LT1 and hope to be racing it here in Sweden in D/SA next season, but when establishing the legal weight we come across different shipping weights depending on whether it's a "coupe 2 door" or a "coupe 2 door W/TH.
I initially thought TH stood for TurboHydramatic, but the different weights appear also under "manual transmission", so what does the TH stand for?

350 350

auto manual
360 360

3341 3341
3397 3397

325 320
12.19.02 1.1.15

I would be very grateful if you can tell me the difference between the 3341 lbs and the 3397 lbs.

Thank you!
