Exhaust Woes

So I recently picked up a '76 Scout II either a 304 or 348 it has either a 2210 or 2245 Holley carb with 4wd auto trans.

It hasn't been run in at least 5 years, possibly longer. Did standard prep, and after I found out it had compression I did fluid changes. Rigged a gas can as a temporary fuel intake and had it running with throttle assist.it had difficulty keeping itself running. After just a few minutes I noticed a decent amount of smoke emitting from the engine bay. Figured it might be some of the gunk on the engine head, various leaves and what have you. This was until it started to smell pretty bad.. Almost like dry metal cooking. So I turned it off and noticed it was coming from just below the spark plugs on the passenger side of the engine. I figured maybe there was a leak in the exhaust, but I didn't understand the smell.

This is where all the smoke was coming from:

I decided maybe the engine just needed to cycle more to get the old oil out of the cylinders and ignored the smoke and kept it running with a little bit of throttle. God it smelled terrible, but I figured it would help. I stopped after 8 or 10 minutes and it managed to idle by itself for maybe 30 seconds before stalling, this was not the story earlier, it would stall immediately after stepping off the throttle. I patted myself on the back and figured I did something right.

Just before work, I go to put the cover back on the car and notice hair clippings all over around the truck. At first I thought it was just somebody who didn't know what a trash can was, but then my detective sense kicked in and I smelled it. Same fucking smell from the engine bay!

This came out of my exhaust:

*and I would say there were 5 more clumps about the same size scattered around the right rear exhaust*

what should I do? Stomp my foot and burn up what's in there? It looks like the insulation from the headliner. A critter must have made a rat nest in the exhaust manifold I imagine. The truck has two mufflers after the engine. I believe they are separate both left and right. The clumps only came out on the right side. I don't know if there's a dead animal in there either, but I imagine the back pressure is probably why it isn't idling properly.

Any advice to solve this problem would be greatly appreciated.

Thanks in advance,

Yeah that does look like headliner insulation. I don't know how flame/heat resistant that stuff is. Probably not very. It would be a major bitch, but I think your safest play would be to disco the exhaust components on both sides including the manifolds and manually remove as much of that crap as you can. You might find a crispy carcass or three in there as well...yummy:icon_xp: engines don't like overly restrictive exhaust systems, as you've now witnessed first hand.
