How long does the 4.6 last?

I used to own a 2001 Mustang GT 4.6 Romeo block, but the engine seized on me after 130,000 miles. I am looking into buying a 2003 Mustang GT with 60,000 miles. I just want your feedback on how long you think these engines will last with perfect maintenance and if you own this engine, how many miles you have on it and what was your biggest repair done to it?

my Cobra has over 200K miles on it, it runs perfect to this day...my Dad had a Crown Vic with over 200K miles on it, it never had a wrench turned on it besides new spark plugs...change the oil religiously, the engine will last forever

There's a couple of Towncars in my family with around 225K on them, still running strong and have never needed major repairs. Ford really had their sh!t together the day they designed these engines.

Thumbs up

My 96 gt has over 256,000 on it and still runs strong! But I am looking into an engine swap, that high of mileage does worry me.

I bought my 2002 with 33k miles on it and it has 104k. It probably has about 120 passes down the track as well. I never had any big repairs honestly.

I traded in my 2003 GT with 63,000 miles on it. I had the oil changed every 3000 miles, and other than fuel, one set of tires, and a control switch for my A/C, I had zero problems with it.

00 GT bought it with 77k and has 90k on it now.

only had the infamous intake manifold crack, replaced that and currently dealing with a misfire on 4.... but just got some accel cops hoping that fixed it. aside from that; its a great running beast with only a CAI. love the car

I've got a 00 gt vert with a host of go fast parts on it, bought it back in 06 with 30k miles on it and it now has 70k and about 100 track passes plus the occasional or frequent street abuse and it has never had an issue other than the norm ie clutch replacement and iac change.

If by "cookie", you mean box full of rubber dicks, then there's one on the way.
