You will need to track it down for the specific year of your engine. I was trying to set my 350 at 10 degree like the builder book said ,and it was no-joy. On here(this site) i found out the 68 350 had a timing of 4degree. After i had a starting point i was able to crank it so it was all in by 3200 rpm`s. You can get basic timing by cranking it forward until it struggled to start. Then turn it back it it start.
Hope this is of some help to you.

ther is no way to really put an exact degree of timeing for any of our older engines, the stock recomendations are going to be wrong due to any modifications in the cam, and stretched timeing chains usually will have 4 degrees or more of slop.
if u can power brake the car without pinging then u can usaully add more timeing, this is only a back yard method,but it can get u in the ballpark, to do this tho , the car needs to be up to operateing temprature

I picked up the car subframed as an early restore project, and unless I get the engine #'s to investigate its origin, I'm guessin' mid seventies. It has a 400 trans , so maybe its out of a p/u. The car idles best at around 12 degrees when its warm. I usually let the engine tell me what it wants. Any reason I shouldn't listen and comply???
