#156 of 175 Had to get the old car mags out for this one by mmcnamara May 15, 2007 (6:09 pm)
Here are some stats from Motor Trend and Car and Driver tests, circa 1971/1972, I'll let the reader decide what he wants to take from this info.These are merely speed/revs figures, not 1/4 mile times.   1971 440-6pk Road Runner, 4.10 rear   104 mph5400 rpm   1971 383-4v Road Runner, 3.55 rear    98 mph5000 rpm   1971 440-4v GTX, 3.23 rear   110 mph4700 rpm   Interestingly enough, this '71 GTX did list a top speed of 130 mph 5500 rpm (redline).   Another article from Motor Trend compared three different 'Cudas, a 340 auto, 440-6 4-speed, and a Hemi auto. The 340 was the author's favorite, as the 440-6 was just too much of a chore to drive, its carb setup impossible to modulate between moderate acceleration and flat-out. The Hemi was easy to drive, also, just keep your foot out of it on takeoff. Top end on the cars (all at redline): 340 (4.10 rear)- 101 mph, 440-6 (3.54 rear)- 109 mph, 426 Hemi (3.55 rear)-112 mph.   Surmise what you will, but I drove some of these vehicles on a daily basis, and trust me, by 100 mph, they were mostly used up and acceleration was pretty slow thereafter. Here's a shocker- Car and Driver tested a Saturn Aura XR that was quicker and faster in the quarter than the '71 GTX! As far as I'm concerned, the golden age of cars is now.

Replying to: mmcnamara (May 15, 2007 6:09 pm) Wow, those top speeds really are kinda sad, although I guess with those really quick axle ratios, they're just not going to get much of a top speed as they're really screaming by the time they hit 100.   I'm kinda surprised though, that the car with the 3.23:1 ratio only made it to 110. I figured a ratio like that would be a good enough "middle of the road" ratio to give good top speed without hurting acceleration too much.   Sad thing is, though, that I had an '89 Gran Fury ex police car, with a 318-4bbl and a 2.94 ratio. It would top out at about 120 mph, according to the Michigan State Police, at least. Heck, even my old '69 Dart GT, with a 225-1bbl and 2.76:1 axle could break 100 mph pretty easily. I was afraid to take it much higher than that, though. It actually felt like it had plenty of power left at that speed, but I have a feeling it wouldn't have gone much faster.

Replying to: andre1969 (May 15, 2007 6:32 pm) I use to work on the Gran Fury police cars,and would help calibrate the speedometer and would top out at 115,then we would flip over the air cleaner and get 120 out of them,it was a old trick we would do to get more speed and help the MPGs.I also worked on a '70 Fury police car with the 440,and it had 2:76 gears,I don't know what it top out at,but is was the fastest car I worked on ,the road test were awesome.I also had a '68 Road Runner with 3:23,and one time dragging a Vette I was doing 115 in third,shifted to forth and buried the speedo,the speedo only went to 120,so I don't know what the top end was,but is was fast.BTW the Vette beat me,but it wasn't stock.I would beat most stock vettes with the Runner.

Replying to: andre1969 (May 15, 2007 6:32 pm) I think you're right about the wind resistance factor, although I'd have to drag out the old physics texts to be sure.Really makes a difference when trying to get that last 10 mph, no doubt about it. And as you said, those big blocks with their 100 lb. cranks and 2 ft. strokes just don't like the top of the tach.

I have an old '68 Dodge Dart V-8 air cleaner top that I put on the Chevy. It has the tall 5" or so air filter, and the top part is actually too big to flip. But the Dart's air cleaner, which is flat, sits nicely on top of the air filter and exposes a great deal of it.   I don't know how much it REALLY helps acceleration on that dog, but it does seem to take off a bit quicker when trying to merge onto a highway, for instance. And it seems to improve fuel economy a bit, maybe .5-1.0 mpg. Which, when you're dealing with maybe 12-15 mpg to begin with, every little bit helps!   It does make it a bit crankier in cooler weather though, and I have a feeling that it screws with emissions.

Replying to: andre1969 (May 15, 2007 7:24 pm) During the winter,we had to flip the top back to normal.One reason was the engines would bog down because the air was to cold,plus fear of snow getting into the engine.Some emissions would be blocked off to gain power.Back then we didn't have emission testings.Plus we would take off the resonators to gain power.There were lots of tricks,thats why had the faster police cars.

#163 of 175 Ford "SuperSnake" Recreation by bflavell Jul 03, 2007 (7:32 am)
Jeff Yerkovich, owner of R&A Motorsports, one of the country’s leading restorer of Shelby Mustangs, CARSTAR in Riverside, Kan., re-created the “Super Snake,” a legendary experimental car produced by the Ford Motor Company in 1967. The prototype, never offered for production, featured Carroll Shelby-modified Mustang chassis, suspensions and bodies with big block motors delivering more than 400 horsepower. The renovated vehicle carries the Wimbleton white and blue stripe livery of the original vehicle and is authentic down to the paint drips and over-sprays on the chassis and undercarriages of the original cars.   The car is still awaiting Shelby certification and is currently on tour with CARSTAR making $$$ for the Make-A-Wish Foundation.

Replying to: lambolover (May 18, 2007 8:20 pm) The Camaro is being built on the same platform used for the Holden Commodore/Pontiac G8, and the V8 version of that clocks in at just over 4,000 pounds. The Camaro will be shorter, but not enough to bring it under 3,700 (and probably not under 3,800 now that we have the G8 numbers).

Just came across this person's carspace page - really great illustrations in his album that he says you can download/use for free: http://www.carspace.com/bigblockrulz
