the speedo will go to 105, its off from my tires, and hell it will burry 120 if i just want to hold the trip reset for about 30 seconds while turning on the key then 30 seconds after the key is turned on the guages will all max out and i just scroll threw the options and get to my tach. too bad it cant hit 120 until i have the speed limiter removed.

just like if you compare a chevy 302 and a ford 302 ford wins hands down (starts new arguements because chevy guys gets pride hurt to easy)

I'd rather have a Chevy 302 instead of a Ford 302. The Chevy one I beleive made more power than the Ford 302 ever did, from the factory.

it was the other way around the ford one made more power, more torque and even sounded alot better, the chevy one fell on its face much like there 305

Is it too late for me to say I'm ok with my 4.6??? Would I like the 5.4, that's a toss up. If the 5.4 didn't have the injector or plug issues then definitely yes. Don't get the panties in a bunch over that comment, it's simply an opinion. I know those issues aren't as common like the bearings spinning in the ol GM 231's back in the 80's (bit more than a few friends back then) but those things are a deterrent for some who are paranoid of such things. Wait a second, what was the topic...

Have you ever even seen or heard a chevy 302? Do you know when they were made because they arent exactly "common". Alot of chevy guys will put that towards the top of all time best engines. And as far as "falling on its face"-those things could rev to 7000rpm stock. Try that with a Ford 302.

Please do everyone on this forum a favor and sell your truck and buy a civic. You will fit in much better on those forums and then you can start a thread " My 1.6L is faster then your lawnmower".

I finally agree with Ridge on something.

Boss 302 > Chevy 302

Read an old article about a Ford Boss Mustang owner with the 302 in it. The article title was "My car likes to fart sparks" It was basically a review of the car from a car&driver guy. They were running 12's in the quarter with it, that is faster than most big blocks made in the 60's-70's

Personally, I don't see the 4.6's having enough ooomph to go past 120MPH... with a tuner of course.

I need some hard evidence to believe that. Even with straight pipes and an open air box...

EDIT: I MIGHT beleive it, but it would take a long, long straight away.

you cant be serious? the 4.6 will hit 120 pretty quick i can do it with half the pedal (i know this because ive toped the truck out at half the pedal), if i want to get there fast sure i can floor it, but once again im talking about a single cab truck and your talking about a super crew, which they can still hit 120 without a problem. the motor has plenty of power to do this. hell ive seen corollas hit 110. surely a 4.6 150 can hit well over 110.

Wait, you're running a stock PCM thats been 'tuned up' so did they remove the rev limiter as well to allow your 4.6L to get to 120 mph?

ive seen plenty of 302's and im still saying a ford 302 will walk a chevy 302, when ford put the 302 in the mustang they said they had enough to work with to get close to around 300hp out of it, however the had to moderate this for gas mileage.

also 7000 rpms isnt much considering a stock forged steel Boss 302 crankshaft will handle 10,000 rpm before centrifical force flings it apart. (This has been documented by Coates Engineering during their rotary valve head development)
A stock cast iron 302 crankshaft will handle at least 7500 rpm, though I wouldnt bet on its integrity at that speed,the same way with the chevy 302. ive herd of people holding stock 302's at redline for as long as a full minute, redline in a 302 is around 7500 i belive, and the engine held out. why was they doing this?? who the hell knows.
