HELP Pricing and advice!! V6 rebuild or upgrade the motor???

I am the proud owner of a 2004 40th edition automatic 3.9L Ford mustang. it has ORH headers, long tubes, and flowmaster 40's with dumps. But sadly my precious mustang needs to have the motor rebuilt sometime. SO should I spend the money to rebuild the v6 or upgrade to a v8, or a 5.0 or cut my losses and sell the car and buy something else? Im in Oklahoma if that matters for any of the laws. This is the first time Ive ever had any problems like this so Im very green on this. Absolutely any and all advise is helpful.

I was told by my dad who took it to the shop for me (because he wants me more worried about school dumb right? kidding) that the seals in the bottom of the motor were ruined. To fix those it would be the same as rebuilding it, or replacing the motor. Plus this is the best opportunity i have had to throw a big ol beefed up engine in it.

drop the transmission replace rear main seal,remove harmonic balancer from front of crankshaft replace seal..change oil and drive for a long time 5 hrs tops labor, $30 for seals $25 for oil and filter, shouldn't cost more than $400 depending on who does work,you do not want shop that told your dad that you needed to replace engine to touch your car ever again. he's a rip off artist or just plain stupid. maybe just needs a bunch of money for pulling your engine and replacing gaskets and seals cleaning up and re-installing. telling you that you have new engine..

If you didnt want to try to fix it or just want to put a beefier engine in you can look for a 04-05 Crown Vic PI 4.6 V8. They can be had for low miles pretty cheap, like in the $500-$1k range from what ive seen. There are members on this forum that have done this and it works quite well. Im not 100% sure how your trans will mate up to the PI motor but i dont think its that bad at all, im sure somone will chime in with that info. If you can do the work yourself you could do this for less than a grand for sure or find ANOTHER shop to take the 6 out and drop in the 8 if your going to spend money on an engine rebuild anyway, the cost probably wouldnt be that much more. Im sure once you do your research, and possibly get a 2nd opinion on your current motor situation you will figure out what you want to do. If you want more power and upgrade to a V8 then this would be the easiest most cost effective way IMO.

Cut your losses and call the bank. Sell the trans and shell if you can.


It takes a LOT to turn a V6 into a GT. Just save money, and then take out a small loan and get something you don't have to worry about..


You're gonna need a second car even if you do decide to convert the V6 to a GT..


Or keep the V6 stang as a project car so you can just build whatever you want throughout the next 10 years. Do it on the side while you're driving your shiny V8 car not worrying about anything but basic upkeep and how to make the exhaust sound radical
.



Ill let you in on a secret: Most of these projects are never 100% done.

The oil leak was my pan and I fixed it. But there is oil in the actual motor itself. But it's misfiring in the 3 and 6 valve
