Thanks Cantflip, I'll do just that. It had a miss on one of the cylinders. Turns out one of my new spark plug wires was a bit broken. We fixed it, and now it doesn't miss.
I'll keep listening to it pretty closely. Anyone know of somewhere i can get a replacement fan for my engine? The one I got is starting to squeak like crazy.
Water Pump?

Yeah the water pump fan.
Also could someone do me a favor and take a picture of their driver's side engine mount? On an LA engine. I wanna see what one looks loke when it's right
Are you 100% it's not the bushing in the pump, or does the fan clutch make noise when you turn it by hand? IDK, but I would have believed these to be off the shelf items at a local parts store... maybe I'm just showing how long since I last owned a 318. Both are easy fixes.
As to your MM questions, I didn't see anything wrong in your pics... IDK for certain, but your left engine mount may be slightly offset for steering gear clearance... what exactly has you concerned about it?

I'll double check. I hadn't actually considered the bushing in the pump. The fan does squeak slightly when turned by hand though. I think it is the fan but now it would be a good idea to look into the water pump too. Especially because of how easy the installation is.
My dad has been pretty concerned about that mount for a while. Today one of the bolts started to make its way loose abs the engine developed a noticeable wobble to it. We're looking at doing something with that.

You did soak the lifters in oil before installing them, yes?

No, I did some research and it seemed like just oiling them up was all that was necessary. I guess it is better for the pushrods if the lifters are allowed to pump themselves up. That's what I read anyway.
Is it better to soak them?

That is how I have always done it. I was told long ago by a guy who taught me a great deal about all things automotive that it's necessary to soak them to purge the air out and give them a head start prior to installation. I let them soak, standing upright, completely submerged in oil, for 24 hours. I am still not certain if it is absolutely necessary, but this is the procedure I follow, and it has worked well for me.

I'll try that next time.
Well my knock is back. This time only when the engine is accelerating though, so it could still be valve related. Can't tell right now if it's getting louder as the engine runs though. I'm keeping an eye on the oil level and the radio off to listen to the engine. Guess I'm gonna be pulling the engine to rebuild it sometime here then.

This time, lets see if we can pinpoint the problem. You may need to spend a little time on a fresh diagnosis rather than try to answer this from memory.
How does engine temperature affect the noise? Do you hear it more cold or after the engine has run a while?
While the engine is running, does the noise seem to match the rhythm of just one cylinder or several?
You indicated the noise is load related (acceleration)... that alone rules out anything valve related.
Just to rule out something simple... double check that the spark plug wires are in proper order, please.

Alright, I believe it becomes more noticeable when the engine has been run. After I got home from work last night, after the half mile hill climb I could hear the knock at idling speeds. But this morning when I started it up the knock was gone at idle and only began sounding at around a quarter throttle.
I can't really tell if the noise matches one cylinder, but for some reason it sounds like it's coming from the passenger side of the engine. If I had to say where precisely I'd say it's coming from around the front of the passenger side. But I'm not really 100% sure.
Yesterday I pulled the sparkplug wires and reseated them, so they should be making a good connection, But does anyone have a diagram of what order the wires should go? I'll try to look for one.
Thanks Cantflip, Your help as always is appreciated.
Use a big screwdriver as a stethoscope to zero in on your noise. Just steer of the ignition wires, fan belts and fan. I've also used a 3' 3/8 drive bar extension with good results.

Thanks guys, I got a new bit of information I noticed. It seems the knocking is only really noticeable when the car is parked in neutral. When I'm driving and I give it gas I can't really hear it. Part of this is the road noise but that couldn't cover up all the noise. Any ideas why that might be? A lady at the auto parts store thought it might be related to the torque converter... could this be possible? I don't really know anything about the torque converter so I'm not sure.
Also I could get about 19 quarts of 20/50 oil for two bucks each. It is semi synthetic though (not full synthetic) will that still work? My local auto parts store is trying to get rid of the stuff and I was thinking it might be better for my engine if I switched to a heavier wieght oil. (The knocking is less pronounced when the engine is cooler and the oil is cold, so maybe if i switched it would mute the knocking a little. )
Right now my dad thinks the knocking might be a piston bearing, that plausible?
Also, I got a short story for you guys about what happened to me earlier today at the auto parts store. After I pulled in and chatted with the lady who owns the store one of her workers asked me about my Fury (it was parked outside). I told him I'd shipped it in from Montana and that its a pretty nice desirable model that needs some work. The guy (around my age so mid twenties) said he doubted any of the old Furys were desirable and that they handle like trucks. I told him I could take my car down one of the really windy bluff roads doing 40mph down it without trying. Anyhow that's sort of the gist of it, I couldn't tell if he was trying to be rude, or was just kind of awkward. Coincidentally he is a Ford guy and he was driving a mid 90s escort that was more rust than car.

Since you say passenger side, I have heard the heat riser valve in the exhaust manifold make a knocking sound at idle. Easy enough to check. Just reach down and feel if it's really loose.

Actually funny that you mention it, that heat riser is knocking, but it makes a higher bell-like sound. My engine is making a sound like a dull hammering.
You know of an easy way to stop the heat riser from rattling?

When you had the oil pan off did you check the rod bearings? Dull hammering sounds like it could be a rod bearing that has spun. When you lightly free rev the engine does it make the knock on decel? The heat riser can be welded in the open position.

Knock on decal?
Yeah when I have it in neutral and Rev it i can hear it knock. But when it's in drive i can't hear the knock. Does that seem like a rod bearing?
Tomorrow I'm gonna rule out a loose motor mount and maybe later this week check out the torque converter. Thanks for the help again guys, I'll report back results.

Sorry decel, sounds like it's just starting. Has it gotten any worse since you first heard it?
2 questions
A. Do you have the ability to post any video/audio .. maybe a go pro from engine compartment (might need hood off for optimum video/audio) for a test drive? If that's not possible maybe a remote mike under the hood on test drive?
2. Would you perhaps like to rename this thread to something more personal
. Your title is fine if you like it. Just offering to change it if you want. Maybe something like ' The Fearless 71 Sport Fury - See it if you Dare ! ' or ' Fearless Fury, The Sport - 1971! " or whatever.
