TBI Upgrade
OK I am new here and have read so much. I want to upgrade my TBI to a holley 502-5 unit. A lot of what I have read says I need a spacer/adapter. Then I would have to change my filter assembly. Performance improvements says it shows as a direct swap has anyone done this? I have an 89 L03
