This is posted in several areas as it's belonging in the areas.

The motor is a FE 360, 4b. carb and looks all original. Also running straight pipes so Im sure the cats arent clogged, heh.

I thought the bogging may be because my carb is open and may be sucking in hot air, as the bogging starts when I shut the hood while the truck is hot. -Good timing? Still possible since I didnt have time to test out that theory today.

I also read somewhere that a bad Alt may present some bogging as well, and since it looks pretty old, im assuming that it is. I was told to test out the alt by removing the pos. cable from the battery when the truck is running, it died. Confirms my dead Alt. theory, but since I haven't replaced it, im still curious. EDIT: Isn't the Alt.

Another theory I read is the water pump could present the bogging if it's old and worn; it looks pretty much like that. So I figure there's another possibility that I can follow. To futher this, I also notice the radiator making noises as if the water is settling, could be normal, but I never hear the same noise from the other four vehicles, so it's questionable.

To follow up on that, I hear the head gasket could be another culprit to that, but I rarely get smoke once the truck warms up, and from what I read, the smoke would intensify if there is a head gasket leak. Plus leaks would be visble and I hear the oil would be contaminated, and/or leaking.

So, I have a few ideas, but would hate just just dump parts into the vehicle if they are still good just to hope the problem gets fixed. Any ideas on the bogging. The vac. hose have been checked.

Just thought Id get an early start on my questions before I got to work on the bronco.

Thanks,
