  • Factory TB gasket opening size

    Does anybody know what size the TB openings are in a factory LT1 gasket? I thought I had a spare around here, but I dont. Im looking for something to use as a template for opening up my TB openings in the intake. I know the factory TB is 48mm, and the openings are 52mm in the intake. My TB is a 52mm, but I want to open up the intake in case I decide to grow in the future. Thanks Eric L

      What do I do with the hole for the IAC? Got any pics of yours with the TB off. Eric L
