I definitely liked the 4.6L in my '97 SCAB 4X2. Gas mileage was fairly poor in the city, but it did well on the highway. I never had any problems towing a trailer through the mountains, either. In a Super Crew, I do think the engine is woefully underpowered for the weight of the vehicle.

The 3V 5.4L in my 05 Super Crew FX4 gets just two MPG less than the '97 SCAB did. I get 14 MPG city, 21 MPG highway (55 MPH) and 19 MPG highway (75 MPH). The extra power of the 5.4L is definitely worth the small dip in fuel economy. I drive with a light foot and I'm not hampered with those environmentally friendly blends of gas. I imagine my MPG would be much lower in MI or CA.

 

'cause it was in the truck my wife and I fell in love with!

No regrets.

 

I had a budget when I bought my truck, I know that will surprise some of the "sky's the limit" crowd.

First I drove a 5.4 XL, then a 4.6 XLT - no contest. Love my 4.6 XLT.

You need not believeme too! mine was able to do 19 -20 MPG on easy freeway at 65 - 70 MPH with 2 persons and load with a lot of camping stuff!

Mine is a 04 FX4 Scab with 53,500 miles using 87 gas

 

Not a good analogy considering the PSD option is about $5K.

Besides my 5.4 can kick your 4.6's azz and gets 21MPG

 

Saw it. wanted it. bought it. nuff said.

 

If you want to loose to the 4.6 come to central cali.

 

My 4.6 does what I need it to do with no questions. Gets 15-17/town, 18-21/hwy with 3.55 gears in a '99 SC Lariat. The 5.4 would have been nice towing the boat, but I can run 65-70 down the interstate with cruise set and OD on pulling a 19' boat on a tandem axle trailer (towed load =4200lbs) and 4 adult passengers. She downshifts on anything over fairly flat land and I kick the OD off to help the tranny, but hey, I'm rolling nearly 5 tons with 220hp. The only wish I had was that the 5.4 in '99 came with a bulkier tranny and rear, but mine does well and has been 100% trouble free for the first 75k miles and I expect over 200k out of it.

More power would be nice, but I have no real complaints.

 

When I went to get my truck I test Drove a Screw with a 4.6 and It just didnt feel like it had any power at all. It is a really good engine but I dont think it's a good engine to put a Screw. My dad had a 97 with the 4.6 and he put 150K on it before he sold it. That was a 150K of pulling water trailers and pure torture. If I had a older style f-150 I'd go with the 4.6 without a doubt.

 

If I remeber correctly the 4.6 first showed up in 1993 in the Mark VIII. It might have been 1995 I really can't remeber but that was one hell of a car.

The first 5.4 was in 1997 so the 4.6 has had a little more time to mature than its big brother.

I was looking to buy a truck in 2002. I test drove both (reg cab) and the 5.4 was so much stronger that in 2005 I didn't even consider the 4.6 for a screw.

Get a tuner and the 5.4 comes alive and makes the 4.6 look pretty silly. Not that the 4.6 isn't a good motor.

 

I bought my 4.6L SCAB XLT on Oct '04 near the end of the sales year. I was on a tight budget and also the inventory was limited. The only thing on the lot that met my needs (price, color, options) was a 4.6L XLT SCAB.

It was listed for 29,100 and I got it for 19,300 after rebates.

I don't do any towing, but do fill the bed quite often. The heaviest thing I haul is 2 cu.yard. of mulch, which is quite heavy, but the truck meets my needs for that.

Was disappointed with the acceleration at first, but after a few PCM reflashes, it runs much better now.

Bottom line: Happy with my purchase and love my truck.

 

I think thats Austrailian Metric HP rating.....

2004 GTO was 5.7 350 HP

 

Two reasons i went with the 4.6:
1. I really liked the look of the STX. The front looks just like the FX4. However, you know that the STX does not come with the 5.4.

2. After reading many threads on here and knowing people who had the 5.4 and the 4.6, I believe that the 4.6 is a more reliable engine.

My 4.6 has more than enough power for my Scab. I do have the 5.5' bed which makes my truck only slightly longer and heavier than a regular cab.

 

Well since i have owned both engines in the two trucks i have had I can say i like the 5.4 better except for the gas mileage. My 4.6 in my old truck had plenty of get up and go but my new truck with the 5.4 has even more get up and go.
