oh well there is the problem. yes the 4.2 is not a good choice for an ext cab. my bro has an 03 and it is decent but its ext cab and auto. there is a BIG difference between auto and manual in these trucks. also the gearing is a HUGE difference. i had an 04 heritage reg cab longbed 4.2L manual 2wd and it weighed 3897Lbs. it had a 3.08 rear end. only mod was cold air intake. 0-60 was 9.58 seconds. now i have an 08 reg cab shortbed 4.2L manual 2wd with a 3.55LS rear end. it weighs 4364Lbs(with towing package), only mod is the intake i had on my heritage is now on the 08. 0-60 is also 9.58(at the quickest ive recorded, also there are 2 shifts before i get to 60mph) but 0-100mph is about 5 seconds quicker in my 08 than my 04 was even tho it is almost 500Lbs heavier. that is a big difference to 100. the 08 would be quicker to 60 if i didnt have to shift to 3rd between 50 and 55. my 04's 2nd gear topped at about 65mph. i have ridden in a 5.0 reg cab shortbed 4wd and yes it did get up and go, to a point. i also had a 78 2wd f150 351W with a 4spd manual but it was geared very low. 3rd gear topped at 35mph then 4th went up to 90. lifters would rattle going into 4th every time, but it never actually had trouble. it was not quick at all, but it would pull a hell of a lot. that was back when they were around 165hp. not saying the 5.0 sucks, just saying its not even close to the best.

watch it, we'll come up there and slap you with our rear seats

so what are you saying, the auto is better than the stick or vice versa?

oh i know its not the best, it is damn reliable though as is the 4.2 and 4.9, just cant wait to upgrade

well i think an auto with 3.55 is gonna be quicker than a manual with 3.08 but thats about IT. manual will almost always be quicker.
and you can TRY to come slap me with your rear seats, i'll hit you with my 4 doors, LOL. i have no problem with an extended cab, just think they shouldnt have offered the 4.2 with them. then again, i think they should have dropped the 2V 4.6 a long time ago. and now that they have the 3V, they can either drop the 5.4 or try to make a big jump in it too.

you call those tiny *** speedbrakes "doors"? lol

well ive got a manual with 3.55 so i win! The extra few hundred pounds of an ext cab isnt that bad for the 4.2

Your truck looks busted. Shut up. Go find another forum to post in.

The 4.9 has 265 ft/lb torque but it peaks at something insane like 1800 rpm. It had up to about 150hp, but the redline is also insanely low - taking it over 4000 is just going to make noise. The 4.2 and 5.0 is good for 5000+. You drive a 4.9 like a diesel.

yeah my 04 heritage's 4.2L had a rev limiter at 5400rpms, my 08 has the limiter at 5200rpms. im guessing they were both made to limit at a lower rpm than autos are??? dont the autos go above 5500?

Nope. The 4R70W will be limited to 5400 rpm on any engine because of torque converter issues. There's no point in pushing a 4.2 over 5000 anyway, it just gets very noisy and it's out of breath.

my 04's 4.2 was good power up to the limiter. the 08 once it hits about 4900 it falls on its face it seems. the highest i go is 5000, and it seems to do nicely.

ENJOY!!! i took another 2 hrs of my time to get these.
4.2L
1997-2005 =202hp@4800, 252Lb-Ft@3400
2006-2008 =202hp@4350, 260Lb-Ft@3750

4.6L 2V
1997-2000 =220hp@4750, 265Lb-Ft@4000
2001-2007 =231hp@4750, 293Lb-Ft@3500
2007-2009 =248hp@4750, 294Lb-Ft@4000

4.6L 3V
2009 =292hp@5700, 320Lb-Ft@4000

4.9L
1988-1993 =145hp@3400, 265Lb-Ft@2000
1994-1996 =150hp@3400, 260Lb-Ft@2000

5.0L-
1987-1991 =186hp 270Lb-Ft
1992-1993 =185hp, 270Lb-Ft
1994-1996 =manual=205hp, 275Lb-Ft, auto 195hp, 275Lb-Ft

5.4L 2V
1997-1998 =235hp@4250, 335Lb-Ft@3000
1999-2003 =260hp@4500, 350Lb-Ft@2500

5.4L 3V
2004-2008 =300hp@5000, 365Lb-Ft@3750
2009 =310hp@5000, 365Lb-Ft@3500

5.8L
1988-1992 =210hp, 315Lb-Ft
1993 =200hp, 310Lb-Ft
1994-1996 =210hp@325Lb-Ft@
1993-1995 =240hp, 340Lb-Ft(lightning only)

gotta love K&N, went there and saw a dyno of a 95 f150 5.0L. it found peak hp at rear wheels of 161.88@about 4200rpms. so if you figure the engine being 205 or 195hp it would have a peak at about 4200rpms. i will do this for every year of the 5.0, 5.8 and 4.9 if they have it. it will be an estimated peak hp tho.

well K&N didnt have a whole lot, and i read the 4200 wrong for the 5.0L. so according to K&N's dyno and going by the rear wheel hp and torque, we can guess at the 5.0, 4.9, and 5.8L peak ratings.
here is what they had, and also these numbers are what i thought looked like the peak. they could be wrong, if you want to see for yourself, go to K&Ns website and see. they are also different mileage runs. the 2006 run was made with only 1444 miles so the engine really hasnt even been broken in yet. but the others are made with between 90,000 and 120,000 mile range.

1995 5.0L peak at 4400rpms
1994 5.8L peak at 3800rpms
1998 4.2L peak at 4200rpms
2000 4.2L peak at 4550rpms
2006 4.2L peak at 4350rpms
