1. Ridge, have you ever actually driven past 100 mph?

I've did it alot in my stupider days. Back when gas was <$1.00 per gallon and you could afford to drive a 400-500 hp vehicle that got 4 mpg. The faster you go, the more HP is required to maintain or increase your acceleration. My El Camino SS with 450 RWHP could only go 130 mph...occasionally the stars aligned and I could hit 135-140. That was a gearing and lack of 4th gear issue...and my power band was 2000-3000 rpm, but there are certain undeniable truths. I got there fast, but after 100 mph, I it really stopped pulling hard. The 4.6 doesn't have the power to get to 120 in a decent amount of time.

It would take miles of driving IMO for that motor to get there. I'm thinking 3.55 gears and about 2-3 miles at least if it could do it.

Ridge, you must seriously be spending alot of time Googling motor stuff to try and sound somewhat smart. I hotroded 60's to 80's Chevies for 10 years and have never seen a Chevy 302. I believe they exist, the internet tells me it's true.

Now, the 305, 307, 327, 350, 400, 454...those are "true" chevy motors...not just limited production and/or rare motors. A 4 bolt main 350 bored .30 over, a 400 smallblock crank, 327 camelhump heads with 3 angle done, a 305 z28 cam, Edelbrock Torker II intake, 6:1 roller rockers, long tube headers, port/polish job, and a 750 holly double pumper...that is a bad@zz carbuerated motor IMO...and it cost less than $1,000 to build

your 4.6 won't break 100 with only 1/2 throttle. your speed limiter is 99 mph. your only going to break it going downhill with a tailwind. A PCM "turn up" will get rid of your speed limiter, but your still going to need more than 1/2 throttle. The faster you go, your gas pedal travel goes up incrementaly.

will a moderator please junk this to GD? pleeeeeeeeeeeeeeese...there are actually useful threads with people who aren't posting trivial b.s. because they heard a rumor in timbuckto that it might be true that a 4.6 could outperform a 5.4

Very true tylus! I've had my truck up to 110-120 before and it took way more than half throttle, im sorry ridge but im raising the BS flag on your statement. Tylus that 4 bolt short block you talked about..........

EDIT: Black3V, that was one beautiful Mustang you had

I never said anything about a supercrew. I'm speaking from experience.. The truck below has absolutely pegged the speedo at 120+. It took a while and a lot more than half throttle. And anybody else that has had these trucks that fast will tell you that it's EXTREMELY loud (wind noise). It's like pushing a huge brick through the air at 120MPH.

im sorry but i have hit 100 (ok well 99) from 0 going across our bridge that goes from ky to indiana, and it takes alot less then "miles" of driving, and no you can accelerate to a faster speed over a peorid of time with a steady throttle, and your el comino couldnt go over 130 because of the gears in the rear, and the gears in the tranny. theres a big differnce between that car and a f150, a el comino was made for low end speed, a f150 is more of a everyday truck which would be used on the highways and street. your el comino came with a 4.55 gear ratio, hence on why you stoped going fast after 100. the f150 comes with a 3.55 or a 3.73, that alone is a world of differnce, its also why a chevelle ss (454) would tear up a in the bottom end but is not so good in top end,

and once again while you have not ever seen a chevy 302 i have, hell my best friend has a 67 camaro z28 with the orginal 302 motor sitting in his garage next to his dads 57 chevy, 66 396 chevelle and so on.

ive seen tons of muscle cars, helped build some, and still am around more than you probley would realise.

next question have i been over 100??? i would really hope so... as a matter of fact ive been over it plenty of times. have i been over it in my truck (no not since it tops out at that) in my Ta yes, cougar yes, mustang yes, and a few others.

Didnt you guys know that our trucks were built for the Salt Flats!

P.S. my SUPERCHARGED 5.4 doesnt accelerate for S*** after 100 or so but it must just be geared for "low end speed" and not "every day driving"

um, actually the car had 2.89 gears and then I slapped some 3.73 gears in it...those were later followed by 4.11 gears. I admit, that I couldn't go faster because of my 3 speed and deep rear gears. However, the power wasn't enough to keep pulling hard once your past 100 mph or so. You can still accelerate, but it takes alot more power to accelerate with style.

I think we hold the 0-99 mph Salt Flats record...

A 5.4L truck will absolutely do 120+, but it does take a pretty good distance, and definitely more than 1/2 throttle.

Video of 5.4L Scab

Ridge, borrow a camera and show us how easily your 4.6L gets there.

My SCREW w/ the 4.6 topped out at 118, but that's only because I was running a slalom course at the time.......

But really, with the speed limiter removed via EDGE and running the 93 performance tune I did hit 118. It took a while to get it there. This was on a wide open freeway with little to no traffic. I only did it once so please dont dog me too much

Talking

For me the 5.4 was better...... i was deciding between 2 trucks, a red 4.6 and a black 5.4. They both had the same configuration (super cab), about the same miles (+/- 1000), and fuel consumption was the same (according to everything i read on the net 15 and 19). So, the price was about the same also... the 5.4 was a 2 hundred more, but had the lesser miles. I bought the 5.4, because.....well, i wanted to. The 4.6 is a great, proven engine with great HP and excellent Touque. I had 2 in my mustangs (96 and 2006). I just wanted a 5.4, and to get more HP with the same mpg in fuel....why not. Now if the price was a lot more and the trucks were different i would have not based my choice on the engine size, rather the style of the truck. So, be happy with what you have...at least we were all smart enough to by a Ford....lol
