Post how to make a 140k engine run new

What would I have to do to make my engine run stronger
I know its weak due to the mileage
Would I have to just build another long block
Or ...

It will run a whole lot stronger if you go 12 lbs f/i or 150 shot. Don't know for how long though:p

You basically answered your own question with the mention of a fresh longblock. And unfortunately that's your best option. There is no snake oil, "engine rebuild in a can" available at Autozone I'm aware of that actually works as advertised.

As long as it's not already trashed and you take care of it and don't abuse it, I see no reason why you shouldn't be able to squeeze another 60-100K out of your engine before a rebuild is mandatory. On the other hand, if it's already burning or otherwise passing a significant amount of oil between changes then maybe a rebuild in the not too distant future is in the cards for you.

I was running 11.40's on a 170k mile 4.6 2V in my old GT. These engines will go forever as long as you don't overrev them and bust the ringlands off.

Another big thing about the 4.6 is do not every let them run low on oil I know you shouldnt let any car do it but especially not a 4.6 if not itll last forever and I would say just pull it apart if you dont want to buy another and dip it replace bearings rings and maybe some bad ass trickflow heads and cams I was reading a 5.0 magazine artice and some trickflow heads and cams on an 01 GT added about 70hp to the wheels

1996 Red Mustang GT - Sold back in 2012 after too much time and money was wasted on it.
