I am desperate for any ideas on possible easy solutions for massive power loss on a 1986. I had a bad header leak, so I replaced the gaskets on both sides, I tried the timing next, nothing, so now I really havent a clue why it is this way as before I left it used to scream down the road. The poor truck sat in open storage on base while in Iraq. I checked the electrical system, and everything is well. The truck has a 650 holley carb, that the origional owner placed on it, and it starts up, and revs great. What happens is as soon as it is placed in drive, it bogs out, although it still runs, even when floored, it still bogs, and is just a total dog. Where to start now?
