What would you guys consider excessive timing on a stock 305 engine?

I've been playing around with my timing trying to get rid of a noise which I thought was a knock/ping from the timing being wrong but it hasn't helped.

But tonight I was playing around while driving and with only mechanical advance I have found a pretty sweet spot where the truck seems to be a lot more responsive on the throttle and overall driving.

I haven't had a chance to see what the timing is set at but I will tomorrow but I have a feeling its probably close to 12-14 degrees BTDC maybe more.
