September 5, 2008How many of us out there with a 4.6 motor in a truck, have put another truck with a 5.4 in his place? Were they shocked *or* in denial? Why stop at just a 5.4 motor. Whats the biggest motor in a truck that you have trashed whether it is a ford *or* anything else? Let us speak and be heard.

September 29, 2008the 4.6 arent that good of a motor "speed wise" my stock 4.2v6 5spd beat my budys 4.6 auto with exhaust, both being regular cabs.
September 29, 2008There''s to many variables to this question, and many possible outcomes.
From a 20mph roll my 00Scab LB 4.6 auto with 3.08''s would out accelerate my wifes 01Screw 5.4 auto 3.55ls
From a dead stop the 5.4 would pull away about 3/4''s and then by 60mph my 4.6 would be back dead even with it.
put a trailer behind the trucks (i.e my 18''x83" carhauler and my buddies identical trailer) and the 5.4 will easily walk away.
By the way both of my trucks have almost identical mods. Both have cai''s,tb''s,true dual exhaust,superchips 1715. The only difference is the 00Scab now has 3.73ls where as the 01 Screw has 3.55ls
October 2, 2008Well, some interesting, what I call paranormal events, have happened with mine:
Here is what I have:
4.6L 106,XXX miles
BBK 75mm Throttle Body
AEM Brute Force Intake
Flowmaster 40 series
Auto with the posi rear-end
I have beat a 5.3L Chevy Reg. Cab/ I have stayed with Reg Cab Hemi''''s (yeah, I don''''t understand that one) I stayed a nose ahead of a Duramax Chevy SuperCab spittin black smoke (so he had some mods of some kind) and completely killed a 2005ish F-150 (don''''t know what V- but he was certain he was going to beat me, A Supercrew (once again, unknown V- A 5.0 Flareside F-150, A 5.0 Mustang (I don''''t think that is too difficult), and a slew of 4 bangers (obviously the ones with the $30.00 Autozone mufflers, nothing too spectacular)... And my brothers 4.2L auto. (when he had it) my friends 4.2L 5-speed, and many many 3.8L Mustangs (silly kids)
When I used to work on Harleys they started to get noticeable gains in power around 60-70K miles (cylinders slowly get bored out over time from pistons) has anyone noticed power gains from their F-150s over time, because I sure as hell have.
October 2, 2008ive beat just about every motor I can think about in a truck.
October 5, 2008when i had my stock 4.6 reg cab flareside i raced a chev 5.3 reg cab and got my *** handed to me. 0-60 in a 4.6 is just under 10 secs. and most 4 bangers(anything newer)will kill that. Duramax''''''''''''''''s are around 7.5 secs i would think since the one i drove before(at work) had a full slip tank in it and still pulled hard. Hemi''''''''s are low 7''''''''s you guys must have a different 4.6 than what i had cause mine was slow.
Edit: here''s my old 4.6 truck
October 5, 2008My 5.4 Automatic VS Cookiemans 4.6 5 Speed Manual, trucks are Identical other than that and I had a SI/DO Flowmaster VS his Stock, driving both my 5.4 is much quicker than his 4.6
October 5, 2008redman......weve done a little work to them as well.
October 11, 2008Well speaking with slips... my old 97 F150 ext cab 2wd auto 3.55 open diff ran a dismal best of 17.5 at the track, bone stock. My 99'' F150 5.4 auto 3.55 LS ran a 16.08 with just intake and no name si/do exhaust.
Behind the wheel, they were different animals all together. the 97 was always fuel hunrgy and accelerated slowly, I never called my 97 4.6 ''torquey''. The 99''s torque is felt almost instantly and it''s not as fuel hungry as the 97 was.
October 13, 2008HI!... Well my 2007 RANGER SPORT, 4.0L has never been beat by a F-150 with a n/a 4.6/5.4. Currently it runs 15.03E.T. In a few weeks I''m installing 4.10 gears and a X-CAL2 tuned by MIKE TROYER. Hoping for mid to low 14''s.
October 17, 2008I had an 01'' 150 Supercab 5.4 with a superchip and exhaust that put shame to multiple 4.6''s stop light to stop light. It also threw a ton of 5.3 chevy''s under the wheels, ran door to door with a dirtymax and about two truck lengths behind my buddies built 7.3 Powerstroke.
