I have a 69 Corvette 350, and for that motor with an automatic transmission the book says it is 4 degrees before top dead center. This will give you a starting point but this can vary depending on the type of transmission you have, accuracy of the vibration damper, and the amount of slackness in the timing chain.

According to my camaro manual the early 350's called for about 4BTC base timing. In 1971-72 it went to 6BTC or 8BTC for the high hp engine. In 1973 it went to 8BTC and to 12BTC for the high hp 350. But the majority of 350's from 1971 and up called for 6-8BTC base timing. Now that's what factory calls for. Every engine I've run has almost always been more advanced than called for. Especially with performance upgrades. I'm currently running my engine at about 14-16BTC and she performs just fine.
