The engine in the 2005 Vic is sick. It has 140,000 hard police miles on it. Lets assume that the parts to fix it are more than a $500 Marquis engine I found on CL. 33,000mi and it runs, as in I can take it for a trip around the block before I pull it. I know that a few things would need to be switched like that oil pan and throttle body/intake manifold, maybe a few sensors, etc... but is this feasible, or will it nickle and dime me to death?
What do you think?
Considering the mileage I would consider fixing that car. Take the frount clip off your car and put it on that one. See what he wants for the whole car.
What's ails your Panther?
Not sure yet. Going to get the scan tool out. Maybe on Saturday.
Those cars are nice and dumb. What are you hearing or feeling?
My internal psychic is feeling it is ac compressor related....
I work on my TC all the time as she led the life a $700 car must have before we met and now she knows I will take care of her.
It was a poorly running $500 car. Won't go over 40 mph. Previous owner scanned it and said misfire-bank 1 and clogged cats. Could be as simple as that, but I need to find out myself. Preparing for the worst.
A 4.6 longblock should be a 4.6 longblock, shouldn't cost you more than a gasket set. That said, you're jumping the gun even by my standards*, pop the cats off and see how it runs.
*A near religious following of Murphy's Law, I'm the kind of guy who acquires service manuals for cars I haven't yet bought. I owned a case of 7.62x54r before I bought a Mosin. I don't start work on cars after noon, and I often don't wake up before noon.

Brilliant! 
Already looking at the FSMs on Ebay.
Replaced the COPs yet? 8 for 199 at Summit.
I've had many 4.6s & they seem to be durable. You shouldn't need a new mill w those low miles.
Plugs, cops & fuel filter and you should be all set. Use autolite plugs only.The fuel pumps go around 120-150 k miles.
I'm with Kenny on this. Pop the cats off. Cold be stupid simple. Then work from there.
Bad TPS won't get up to highway speeds, did that a few times too.
Well, the throttle body is different for the P71 (I believe you mentioned that you know that), it is electronic, and I don't know much about it. I assume the sensor is likely the same as the P73. $60? I understand there will be other boo-boos to fix, but do you think spending $500 on the Grand Marquis is going to be worth the labor of pulling and swapping the P71 parts and then scrapping the rest? Personally, I wouldn't do it, but I've done plenty of stupid E36 M3 I wouldn't suggest others do.
A bad TPS would explain the nasty hard shifts and a reluctance to rev. Lack of oomph could be a dying fuel pump.
I love to Seafoam Panthers.
Back in these days:
The turd sammich was flying in to my town to make promises/lies. I live close to the airport & was off work that day, oil change was my plan right after Seafoam treatment.
Anyone who's done this knows how truly gigantic the cloud of thick, white smoke is.....
Suddenly I hear the air being beaten to death over my head! I stride out of the cloud to see what helicopter is attached to that sound and am staring at an AH-64 Apache!
I felt a hot chill and the hairs on my arms & neck were standing up. I threw my hands into the air and ran to my garage. The ship pivoted to keep me in his sights, I grabbed two red motorcraft oil bottles by the neck and as the smoke cleared from the rotor wash, I gave him the "assume guidance" hand signal! Then I gave a "move right" & he did! Then I asked for "lower hook" and he rocked the ship like saying "no" and rotored up & away.
Luckily I had recently pooped so my drawers stayed clean!
Oh yeah, Panthers.....great cars!
Jesus Christ. Lay off the hootch.
I think it's crazy to swap engines when swapping a few relatively cheap parts (and FAR less time most likely) could fix the car.
Not BAD crazy, but just crazy.
In reply to N Sperlo:
Not drunk then.
Just sharing a panther story about how I met an apache.
Should have added that I was scared as E36 M3 & was trying to have him see the car was smoking & I posed No Worries.
I worked on my car this weekend and was therapized greatly. PI intake swap on my 99 TC & finally weather allowed me to tear it down.
I should be more like myself, less berktardish than of late. Or at least I'll keep it to myself better.
Appleseed:
If swapping engines just to swap, 5.4 please. But even an idiot like me can usually fix these quick and cheap, good luck.
but $500 for such a low mile creampuff motor, it's hard to pass up just to have around.
In reply to etifosi:
What year intake did you swap?
So far half-swap...ford racin' PI Intake (NIB) to go in after I decrud things. Ï Thinking i'll have the injectors pro serviced as some got all smoodged up while I rassled with all the snakes under the hood.
