Exactly. It’s acting like it’s got a giant vacuum leak . Lol. But I mean. I’ve swapped sbm intakes countless times in 20 years. There’s not a lot to it. I’ve plugged everything off. I’ve replaced gaskets 3 times. Lol. Ram like a top with 2bbl. As soon as I put the 4bbl. Garbage lol
Take some real close up pictures around the base of the carb where it's mounted on the intake. And different angles of the intake/manifold under the hood. Post 'em
