LT1 stock timing question
Is there any mechanical advance timing in a stock fbody LT1? I changed computers and I'm without a timing mark nor a timing light. I just want to confirm the PCM throws all the timing at the opti or if there is any built in. Stock LT1..
Thanks

There is no mechanical advance nor adjustment on any gen 2 SBC. PCM does it all.
