Fast ratio steering box

Stupid question How many turns lock to lock on a fast ratio and what did they come on? Thanks for any answers.

The optional on any 66 to 69 A-body Fast Ratio 16:1 steering box is 3.6 turns lock to lock.

Same ratio and lock to lock as a standard power steering box/setup.

66 Baracuda
