1969 Barracuda Carb Suggestion Needed

What is the timing set at?
I'm probably going to look like a jack but I have no idea. The previous owner built it for racing and didn't care about anything on the car and most everything has been Jerry rigged. Most of my time spent so far has been fixing everything. I'm only 19 and have very limited knowledge on cars, but I have been learning a lot from everyone here.
