Anybdy heard of this?
 

429 BOSS. What can that engine do? This was takin from another thread and i kinda wanted to drill this guy into the ground
he aslo said this "yea yea yea

all i have to say is ..............COBRA SHOC 427 side oiler

ok 2 things to say ....... BOSS 429

nothing chevy made could touch either of these

SHOC stock produces 1000 HP stock
BOSS 429 produced 750 HP stock

as i said nothing chevy ever made could touch these

and these are HP ratings on stock engines to publicly releaced cars

eat me CHEVY whimps

LoL"
is any that true?

uhhhhh :paranoid:

:confused: :paranoid: :crazy:
you lost me

wut ?

The Boss 429 was from early 70's mustangs, ther were pretty nice. One of only two mustangs i actually want. Think you're off on the hp rating though, believe it was a couple hundred less, but it was still nice

sorry i was in a hurry last night, the guy was saying how the 429 producded over 750 hp stock... i don't know much about early ford motors and i was wondering if that was true

The Boss429 today is about a 70-80K $ car.. The boss429 hp numbers when released was written as 400-500 depending on the options, purely for insurance reasons, and so they could sell the car. Actual hp numbers are estimated between 650-750hp.. this car was simply bad ass...but also barely streetable. Pretty much a racecar right off the showroom floor. I have a chevy, and I can't really think of anything off the top of my head that chevy made stock that could take this car. Mopar and their hemis are another story though...

there was the corvette in the late 60's that was rated at 400-450hp.. but pushing near 600 i believe.... of course i think everyone here can agree its power to weight that matters.. not pure hp numbers.

The Boss429 ran constant 11s street tires.

damn.....you were right when you said it was simply badass. how much did they go for when they first came out?

I dunno.. back then it was probably 4grand if that.. I would like to buy 10 of them..

Would be nice wouldnt it!:eek:

Where in the hell did you find something saying that the BOSS 429 ran 11's on street tires?

Maybe it was 11 on non street tires.. but that horsepower and tq rating is WRONG. As is the ET, and compression ratio.. don't believe everything you read.. "internet says so" doesn't always cut it..

Yes, Mustang enthusiasts are running around spreading wrong specs on their cars, just for fun i guess. So does "V8killimports says so" cut it?! I don't think so.

So how much was car insurance back in the late 60's early 70's? NOT MUCH I'm sure.

its all relative man... dont bust his balls.. they did underrate a few cars for insurance reasons.. i saw somewhere on the internet that said my car ran a 15.5 stock.. but it runs 15.1-14.9 stock. and ive seen more than a handfull of BS on alot of other things too.. its the enthusiasts who research.. know where to look and have been doing this for a while that i would listen to

Ok I looked everywhere on the internet, and i havent found one thing that says or even hints that the 1970 Boss 429 can run anywhere near 11's on street tires or any other tire. Think about it, a car from that era running 11's from the factory. I've never heard of such a thing. One of the bests I've seen is a 1970 Chevelle with a 454(my dream project car) that ran low 13's on street tires.

Do some more research before talking. I owned a 66 stang for 5 years, was a member of many clubs, and got to see these boss429s first hand.. I have heard them run, and can tell that they are barely streetable.. 454 chevelle? nice but not the quickest.. And btw I can name one off the bat.. the shelby 427 cobras..yes..a ford ran low 12.2 at 118mph easily all day long.. so I guess that shoots your 'dream car" down already... And why did they change the numbers for insurance reasons? Well if you did a little reading you could find out for yourself.. but it seems you are too lazy or can't read.. pick one I don't care.. they orig called the 429 a HO429 then changed the name to boss. What was the difference between the boss429 engine ran in NASCAR and the boss429 sold to the consumer? Nothing. They were the same engine.. There were options to swap carbs, and put milder cams in for customers who wanted them, but the 429 was the same designed for NASCAR. I am not sure, but I don't think NASCAR lets cars compete that do 14s in the 1/4.

lol v8...you're a funny guy.

LOL, man you crack me up

NO shit the Boss429 came with a NASCAR engine! So you've had an old Mustang and still don't know shit about them. Dont come on here like you actually know something Like f'g mustangs running 11's back in the late 60's give me a break. Oh yeah, NASCAR gears their cars for straight 1/4 mile times! you moron. They go in a damn circle for hours at a time the're more focused on top speed rather than pure acceleration. WTF are you talking about "shot my dream car down" I didn't say it was the fastest car evermade or some shit.

THATS your problem right there!

You idiot.. I know they are not 1/4 miles times.. use a little logic.. if a car runs 14s in the 1/4 do you think they are even gonna put it on the track? And yes the 429 was a detuned nascar engine.. you seem to be getting a little excited... maybe you need to go jerk off to calm yourself down a bit.. a guy simply asked a question here, and I promise you I have had more experience with this car than you have..

BTW, I don't own this car, you don't own this car, but I do own a grocery getting 94 Si.. sad how my grocery getter could prob put a whoppin on you isn't it?

Well since they're driving 200 or more miles, that first 1/4 probably doesnt matter too much. But hey, I'm just using logic. Why are you telling me again that it was a NASCAR engine, like I said I KNOW its one. Thanks for the promise though.

Ok I will spell it out for you V E R Y slowly for you. YOU claimed that the boss429 did 14s in the 1/4. Let's say they did....now why the hell would Ford use this engine in Nascar? You think they said.. "hey let's use the 429 that run's 14s in the 1/4... I know it runs slow 1/4 but maybe it'll do better for 200 miles". All I asking is to use some logic.. We are no longer talking about the car.. the new subject is how you may be mildly retarded. You said the car did 14s.. you are wrong. Even though the mighty internet told you so.. you are wrong.. Do me a favor, get off the internet.. and do real reasearch.. talk to someone who has owned this car.. read books on it, reports, etc.. BTW I saw on the internet that your car comes with 25hp and does 32 secs in the 1/4...must be true!

Did I say That the damn car ran 14's??? NO i just put up a link to a mustang "enthusiats" website that had the spec, which isn't the only place I've seen similiar times, some as low as high 13's. IN FACT the only thing i claimed is that the damn car doesn't run 11's in the 1/4!!!!!!!!!!!!!!!!!I'm not going to spend money buying books just to argue with some moron one on the internet, when i can easily find the info online.

On a side note, I wonder how long we have til this thread gets closed???

Dunno... I am cool..you are getting too excited though.. the car runs low 12s with street tires.. 11s with cheater slicks. Then we agree then...

I'm not excited, I'm just sitting here at work trying to pass the time. Please show me some proof that the car runs what you say it does then this whole thing will be over.

If I find a website that says it runs 9s in the 1/4 will you believe that too?? I know that 12 seconds will never happen in your civic.. and it's like another dimension to you, but low 12s especially for a big block is pretty easy... Anything under 16 is cosmic to you, I realize that, but you have to realize that a 429 is about 5 times the size of you motor, has massive heads on it, a racical cam, and large volume 4 barrel carbs... not to hard to run 12s.. I run 12s on a sb with less hp.. why is this so hard for you to accept?

How many cars from the 1960-70's run low 12 sec 1/4 mile? That Cobra example you gave earlier was a car that weighed what? Like 2500lbs? Your talking about a Mustang that weighed about 3500lbs. Unless your talking about a different cobra.

there wernt many production cars with lots of hp.. your missing it... that huge amount of HP can push a 3500 lb car into the 12's

66 Corvette 427 - Mid 12s
69 Roadrunner 440 six pack - high 12s
70 hemi cuda - high 12s

You done yet? I told you it wasn't uncommon.. and keep in mind ths is a detuned 429.

94 Honda Civic ex - mid whatever???
You haven't proved much.

You asked a question.. I answered it.. you asked how many 60s/70s cars ran 12s.. I named a few.. and those are very heavy cars..aside from the vette..

I'm not saying that its impossible or anything, just highly unlikely that a production car from back then could run 11's. But prove me wrong, I really don't care. I'm just passing the time.

I took almost a second off my time running slicks.. a boss429 can easily run 11s with traction solutions, and even a bit of tuning can do wonders... anyways off to bed.. you prove me wrong with something other than the mighty internet...

A full second huh? Well I didn't know that slicks could take THAT much time off you ET. If they can, then I agree it shouldn't be too hard to get a car in the 11's if they can run high 12's on street tires. I guess you learn something new everyday.

dude... slicks car on high hp cars that have trouble getting traction will help that much. really, you sound like your not understanding the power of a mucle car.
