When Crockett and Castillo start after the lady in the blue corvette it is obvious that their Ferrari has an automatic transmission when Crockett puts it in "Drive." No Ferrari 365 GTS/4 had an automatic transmission.
At around 23:20 there is an obvious dub where Castillo is saying "let's get going" in a strange gruff voice, but his lips are saying something else. This is in response to Crockett saying "he'll come through."
