Here's the deal, I have an '84 with around 64k on it. I just got done putting on an X-Ram intake. (What a mickey mouse set up that is. If your thinking about getting one, I would check out other options.) I also put on the bored out TBs. The biggest ones I could find. Plus SS Magna Flow System. The problem is that when I step on it, It wants to die for about 3-4seconds then It goes pretty good. It doesn't always do it, but it seems to more often then not. I put a 85 fuel pump in and changed the fuel filter. I also put in new plugs, wires, cap. I think there might be a little bit of play in the distributer shaft. The X-ram site sells shims so it must be a common Problem with the setup. I was thinking about going to a high proformance Cap, but i don't know if it would be worth the money.
