I believe its 6 degrees before top dead center. That's stock, I am modified a bit, and run mine back to about 10 degrees, no knock w/ 92 octane.

Ive got a 1986 firebird 5.0l engine, which i just timed not less than a week ago. it is 4degrees above top dead center with 91 octane fuel. iset my to factory setting which is 4degrees but check under the hood for labels, they should tell you at which degree to set it to
