4.6 triton 5.4 triton

Her truck and mine are within 100 pounds of each other. The new body style 2004 F150s didn't have the blown out spark plug issue. It was the 1997-2003 2 valve engines, but mainly the 5.4; not saying the newer body style didn't have any issues but not nearly as much as the older engines. By the time the 4.6 3 valve came around, they didn't have near as many issues as the 5.4 had. They were already installing upgraded parts.
Anyways, cheers.

I'm not going to argue with you, and I don't have a time slip to prove it. Considering we weren't on the track. Her's was bone stock, mine had a chip. The only difference. Anyways, take it for what it is. It's not like either she or I plan on racing. It was just a last minute thing on a back road. I agree that it doesn't serve much validity, however; for me I'm not too impressed with the 3 valve 5.4. I'd take my little ole 4.6 any day. It's been a awesome part of my truck.
I wasn't basing my dislike for the 5.4 on this drag race, if it can even be called that. However, between changing broken plug, and seeing her bill for changing the timing chains, and VCT solenoids, I'd take my 4.6 over the problematic 5.4.
As far as the weight goes I was simply saying that curb weight for the trucks, isn't that different.

Not saying they are all perfect. However the 4.6 3 valve didn't have as many issues as the 5.4 3 valve.
I agree as far as heavy towing goes. The 4.6 isn't as good. But that comparing a 281 cu.in. engine to a 330 cu in engine. I have pulled 6500 with my truck with no issues. It stays in the high rpms to get going, but after it does so it isn't so bad.
Just overall I'd still rather have the 4.6

The only "issue" the two don't share is plugs breaking. Follow the YouTube vids to impact them out on a warm engine and then apply nickel anti seize on the new ones and it will never be a problem again. Other than that both 3V motors share their problems.

In fact the repair guide lines and parts are the same and list both engines as having the problem.
