1988 5.7 v8 motor question
how would i go about trying to fix the timing? had the motor back in and with open headers it seemed to run perfect but not that it has exhaust and back pressure the timing seems off and it hesitates when i give it gas like 80% of the time atleast. any help would be super appreciated. thought id have all the mechanical stuff done and this and another problem came up. thank you
