I have an old 84 Ranger with a 2.8L V6 and I'm trying to squeeze out as much power out of the engine as possible. The cat had been removed by the last owner, so the pump was essentially just pushing air to nowhere, and the old tube was just hanging and dragging along. I'm thinking I could just remove the entire system without a huge hassle.
I just removed the air pump and fitted a new belt onto the alternator (it was previously driving both the alternator & smog pump on the same belt). Now I'm not sure what to do with the tubes coming from the exhaust manifold, check (it looks like) valves, and all the extra vacuum (?) lines going into the carb.
I think I'm just going to plug the holes on exhaust manifold, but how do I tackle the vacuum lines?
