I have a 502 mag efi motor, blew the head gasket and put everything back together the right way now (bought it with issues), question is, its a stock motor running on low boost, 5 to 8 # iam figuring right now, has a vortech supercharger, question is what should the timing be on that set up to start with????

thanx for any info Jeremy

8* base @1500 rpm would be my answer, call eddie @young performance.
