That might be the suggestion for total, but, once in the car, those dyno timing numbers sometimes go out the window. Might want more, maybe less
Total is one piece, what is the idle timing. That will make a difference in how clean it runs at idle and off idle throttle openings. I'd guess it should have about 18-22 initial timing to run clean.
JMO, you NEVER want the timing to be all in later than the flash level of the converter on a hot street or track car.
