Exhaust Info needed
on my way home from work this afternoon, my 77 f-150 seemed to be moving alittle slower than usual. i have a 351 cleavland, headers, flowmaster dual exhaust, but back onto my point, when i down shift the engine back fires more than usual, moving very sluggish, and is running a high temp, no pick up, hense the sluggishness, and there is smoke rising from my exhaust underneath. im thinking its the water pump thats bad, but i am new to v-8 with the power it has and need alil help. any ideas or answer would be greatly appreciated, thank you. Shawn
p.s. i just noticed now when i try to speed up it makes a popping noise from the intake area?!?!?

It sounds like it "jumped" time or that there might be a plug wire cross-firing either to the block/ground or to another plug wire.
If you have over-revved it lately you could have dropped a valve and the cylinder chamber compression could be blowing oil out of your valve cover gaskets/pcv hole/oil filler cap.

the smoke is coming out from underneath where the header and exhaust pipes meet. i just noticed the popping when i went to test run around the block didnt go very far. doesnt look like any oil being blown out from anywhere. i think it may have jumped the timing, that had crossed my mind before i signed back in here. but im alil worried. i dont have a chiltons so i cant exactly pin point the problem as u can see. thank u for your help, any further assistance would be greatly appreciated, thank you again. shawn

I would check the timing first, then do a compression test to see if you might have a bad valve or a collapsed spring or maybe even a keeper that's been sheared.
Sounds like it's out of time and causing the exhaust pipes to heat up more than normal, maybe even burning some old, caked-up oil/dirt since you say you have no oil leaks.
