I'm a Ford guy without a doubt but the interchangeability of the Chevrolet always has been a sore spot with me and the Fords.
Very little interchangeability with the Fords from one engine family to another. The modular is a little better for Ford but not much.
As far as the 5.4 3V, it has plenty of ass and could have much more if Ford wanted it that way. I'm one that has posted on the timelips racing forum. I have raced my 4X4 truck as a baseline and look for more performance down the road as well. The problem is they need gears and unless you opted for the preferably 4.10's they just dont have enough. They are rated at the crank at 305 HP and 369 Lb ft of torque if I remember correctly. Next you need to determine gear ratio's and weight to utilize that power. As I've already said, gears make a great difference in any large heavy vehicle. All the mags I've seen has the Ford weighing more than any of the competitors vehicle of the same configuration (by a couple hundred pounds). If someone can show me one that doesn't I'd like to see it. So there goes some of the ass also from the Ford. It takes more power to move more weight.
You are correct though about the LS1. If I could add 4 V heads and cams to the Ford from the 4V mustang, like the Chevy can add LS1 parts from its performance vehicles then certainly things might be much different. But if anyone doubts the capability of the Ford small modular motors, check the Lightning sites out and see the results of some light modding and some heavy modding.
So everyone doesn't get upset with me, I do know what I'm talking about. I own and race a 96 Cougar XR7, 3900 lb car with a modular 4.6L, automatic that on motor alone runs near the 12 second zone, purely stock motor, no head or cam work just utilizing off the car Mustang 2V heads and cams. It has gone high 11's on that same STOCK set-up and Nitrous. With that combination the car dynoed at the rear wheels last August 257 HP and 316 Lbs of TQ at the rear wheels on the motor, and 350 HP and 503 at the wheels with the bottle. Not Crank, through the drvetrain at the wheels.
I've been racing that car since 1996 when I bought it new. That car in (Factory stock configuration) set the MN12 Factory Stock record a year ago and ran a 13.89, 13.91, 13.94, 13.97, 13.98 at 97 MPH in the quarter with nothing more than bolt ons. The only factory stock one to ever run in the 13's on the original stuff. 3900 lbs and bolt ons with an automatic, nothing in the engine had ever been apart. 280 cubic inches! My point is they can make good power with just good bolt-ons and tuning. The potential of the 3V 5.4 has yet to be even touched. Only time will tell what the capability of these powerplants will be.
The problem with most comparisons is that they seldom compare apples to apples. That has been a problem with me for a long time in most comparison tests. If you are going to test a truck vs truck, then test a stock 5.4 against a stock 5.3 or 5.6, same configuration (SC, short bed, etc,etc), same gears ratio's, same automatic or stick, and same weight. Thats real world controlled testing. Then you get real actual results.
We all know that there are differences between them so we may have to make concessions there as far as power/weight ratios etc but at least its a fair comparison.
Again I'm just replying to the prior post and not trying to cause a stir but just my persepctive on things as I see it. Bottom line is though, the man has a point. If it weren't for racing, nothing in this world would get better, thats how we learn what works and what doesn't.
BTW, If you have a 5.3, 4x4 SC, shortbed, with 3.55's and an automatic thats stock except for a tune, I'd like to meet up with you somehere and see how yours and Mine stack up on the track. I ran that HEMI with bolt-ons, I'd give you a try too!!
So from me and "Big Red" Keep running them!
