Fastest vintage stang?

[dodgestang]

Anyway, let me re phrase the question (the original question) like this:

Think that that you are on your way the the store or whatever, and suddenly you haft to stop because there is a red light. You are driving a Boss 429 and then it comes three other stangs, one is a 67 GT 500, one is a 71 Boss 351
and the third is a 69 Mach 1 with a 428 cj. You say: "I'll race all of you to the store", "ok", they say (You think you are the obviously winner because you have the big bad boss 429),
but would you smoke them or would you be smoked?

If you have any suggestions of other cars, feel free to add them.

And yeah, I know the question is FUBAR.

//

Since you know the question is a FUBAR why bother asking it. The answer to your question is very simply, the car with the best driver will win. There is a reason why performance is measured in such static ways as 1/4 times and HP (which we all know the measurement changed....but it is static enough to draw comparison from different manufactures and models in the same years). Other forms of measurement are mere conjecture.

A 68 428 Coupe?!?!?!? Never seen one,any body got a pic of one?

They are pretty rare, but not as rare as 428CJ convertibles. I have seen a coupe before but never the ragtop, maybe they were the ones you remember as not existing?

Here's what I show of CJ production in 1968:

The 428 Cobra Jet was introduced on April 1, 1968. A Ram Air induction setup was installed, as noted by the hood scoop and black hood stripe. The transmission options were a 4-speed manual or six-speed automatic. There was an initial run of 50 units inspired by Ford dealer and Mustang racer Bob Tasca's efforts, but eventually 2,253 CJ Fastbacks and 564 CJ coupes were produced.

I recall reading in a Road and Track that the 428CJ was the fastest production Mustang (non-shelby) ever, until the late model Cobra-Rs. I cannot recall the specifics of the tests, but they were a composite of 0-60, and the 1/4, also included a slalom (why the boss-9 lost I figure), and either a 0-100 or a top-speed. I do not recall if they used newer tires or ran them all on bias-plys or what. I merely opined that the 68CJ coupe would be faster since it weighed less and had a lower CG than the fastback.

Anyhow...back to the FUBAR'edness

Ok, well let's say that it's about 1 mile to the store and ALL of them have drum brakes. And of course the 1/4 time doesn't matter here because you have curves.

That's easy.... which ever one I am driving will get there first...

 

[chepsk8]

When I did the two shoot-out articles for Mustang Illustrated, Curt's 68 428 Gt was ripping off high 12's with slicks on a prepared track. Car had 4.30's with a C-6.

Magazine wise, the BOSS 351 was the king on the 1/4 mile for a long time. On the twisties, it all depends on car prep. I'd guess the best STOCK, PRODUCTION Mustang (excluding the Shelby GT=-350's) on the twisties was the BOSS 302, and for absolute top end, anything with a big-block and long gears! MY old 428 SCJ with 3.25's and a 4-speed would do 135 mph easy at 4000 RPM. Never did get to stretch it all the way....

My .02!!!

[usedtobe 67p51d]

I'ld bet that more than half of the cars on that list had some "extra tuning" from the factory.

 

[Edbert]

That list is on a thousand websites. If the tests are not done on the same day by the same driver on the same track they are not very meaningfull when viewed side-by-side. A perfect example is the L71 and L72 Corvette's (both have 427s) being a half second apart. Or the fact that a 1970 428-Torino was faster than a 1969 Shelby 428-Mustang (24th place versus 44th place).

One half second could be anything...humidity, temperature, and track conditions routinely account for that.

 

[mustang_freak]

Ok, thanks for the answers.

Just another question, which mustang would you pick and why?

of:

69 Mach 1 428 CJ
Boss 429
Boss 351
or Gt-500

I would pick the Boss 429 because I just totally love the look of it and the engine.

 

[dodgestang]

I would pick the 67-8 GT 500 for 2 reasons.

1. There is renewed interest in them so they are appreciating faster than average market value.

2. Sorry to say this Carroll.....but they man is getting old. In the immediate months following the unmentionable I expect values to at least double...which would be a perfect time to dump it and buy 2-3 b429s

 

[Hoyt Clagwell]

Um, sorry, but no way a stock Boss 351 and a 4-speed does 160mph with 3.91 gears. As good as the motor is, it doesn't rev to 12,000 rpm.

I also doubt 160+ mph was possible in total stock trim.

Car and Driver, Feb 1971: with the 3.91 rear
top speed 117. 0-60 - 5.8 1/4 - 14.1 @ 100.6


What was it about the Boss 351 that made it quicker (acceleration) that the 429's? Front-end weight difference? 429 breathes better at the upper end? Underrated hp (335) ?

 

[Max Power]

MY old 428 SCJ with 3.25's and a 4-speed would do 135 mph easy at 4000 RPM. Never did get to stretch it all the way....

LOL Cheppie! Those musta been some purdy tall tires you were runnin!

BTW, there sure aren't many Fords on that top 50 list.

One simple word... TRACTION- The 351Boss is an extremely strong runner - but like all 4v clevelands it is known for a bit of a soggy bottom end- it really pulls hard at top end. You can ride it a bit harder out of the hole than a 429scj on stock tires. Dump the clutch on a 429 at more than 2500 rpm and you've got LOTS of tire smoke.

I saw a video of a friend of mine from some years ago at SAAC. He has a 67 GT500 and he mounted a video camera so you could see out the front windsreen and see the instrument cluster... he was doing 140+ in the straights.

Um, sorry, but no way a stock Boss 351 and a 4-speed does 160mph with 3.91 gears. As good as the motor is, it doesn't rev to 12,000 rpm.

Hmmmm sounds like a bench racing argument, 12k rpm would push a car past 200mph The guy I watched hit the trap at around 7200-7500 Rpm, I've gone 145 in my car quite a few times, with a crappy automatic, and 3.25 gears. As a side note, did I mention this was at Seattle internationals road course, not drag racing, it's not like he hit 160 in a stock ride from the 1/4. it was coming out of the last turn @ 70mph (high bank), onto a HUGE straight.

Plus I dont know how much was to make it look cool, and how much was actuall design, but the body on the 71-73 sports roofs are actually really aero-dynamic.

 

[Max Power]

OK, used the calculator and with 27 inch tall tires, he would be running just shy of 8000 rpm. It's a great motor, but 8000rpm? Even free revving, that's a lot, but pulling a 3500lb car through the air at 160mph?

Let's just say I have my doubts. If he did that, I don't think the motor was stock. Not even close.

 

[kblackav8or]

Depends on how tall the tires are. 3.91's do seem a bit low for that speed. 3.25s would do it though.

thats not entirely true either. because look at this website.

http://www.autofacts.ca/classics/fast.htm

when you get right down too it, nobody really knows, and nobody really kept track of that, other then on the strip itself. thats about it.

As far as fastest production car of that time, I would guess probably that Vette. But, I dont know. That is just a guess...

Good Point! I was fortunate enough to be standing at the end of the track when Ashley took the Pro Mod title here in Vegas.

Man, I don't know if any of you have had the oportunity to stand at the end of the track when top fuelers are comin' at you, but it's pretty much like lookin' at the space shuttle coming straight at you full speed...

Looks like a feeding frenzy on the bidding

I have a hard time believing the fastest stock for stock Mustang ever did a 13.6! Makes me wonder who put the list together.

Pretty silly eh? The Supercharged Cobras of 03-04 are faster than that with street tires. Hell my little old 97 Cobra is that fast (SVTs website says 13.7)!
