should I trade the 8 for a Roush F-150?

Faster? Sure!

Nicer? No way!

The 5.4 isn't even a particularly good engine.

I should say nicer than my Mark VIII :(

As far as a 5.4 not being a good engine I think they are a solid engine. We have had 4 different 5.4s in my family and never had a engine worry, however we had suspension problems left and right and some A/C issues but thats about it. I had more problems out of my 4.6 2V than anything else but that was a bad mechanic issue.:mad:
 
Well, apart from the 5.4's being heavy ole' iron blocks, they apparently suffer from uneven bore wear and bad bore distortion at higher mileages, due to greater rod angle.
 
Well guys I have a question. My good friend just got laid off from work and now he is all on me about my mark viii. He wants to trade me his 99 roush f150 extended cab with vortec super charger for my lincoln and me give him 2500 bux. The truck has less miles and he said he was going to put new nitto 555s on the front before we swap if I wanted. The truck has leather interior, new exhaust, lower gears (size ?), bed rug, painted bed cover and it has new brakes, a-arms with ball joints etc. The only problem is drivers seat back will not recline (something is stuck) and it has a torn spot in the driver seat as well. what should I do?

Dificult desicions... I happen to have both vehicles, not exactly the same but close enough. I am DEEPLY in love with my Mark VIII but if I had to give up one of my cars the Mark would have to go. My truck is also a 99 & it is simply an amazing truck. It's way less maintenance than tha Mark VIII as it doesn't have all the fancy gadgets & no matter what challenge I give my truck, it never says no! Whether I pull 2 waverunners in a dual trailer, a 26 ft boat, a trailer with ATV's, pull a tree trunk (yes, even did that!). They are truly built tough!

Faster? Sure!

Nicer? No way!

I beg to differ! Beautiful looking truck, great project, strong engine. I know quite a few people with Harley Davidson F-150s with the Supercharged 5.4 liter engines. They swear by them.

Guys, everyone has their opinions, if you dont like a certain vehicle, you may end up providing negative info, likewise if you LOVE a certain vehicle. Playboy, you have to do what YOU want to do. Your Mark VIII looks REALLY sweet, choose wisely! ;) Good luck!
 
This is a NO BRAINER!

Do it... There are other marks to be had...
 
how abused is the truck. i didnt know roush made one that year. 99 are cheap. how much work is in the motor..hard to get into a used surperchaged car and not know the background.

Regardless of what people swear by, the problems with the 5.4 engines are well documented.
