I've done a lot of talking here with nothing to show, so I decided it was time today...finally....to dig through some photos. I'll add more if anyone is interested.

Nice looking truck! I do have to call 'BS' on the third picture, there is no way you're not holding the brake......You'd definitely move a little if you weren't holding the brake.

 

do ya have any more??? under hood interior etc...

 

Ha..Ha....

Well, the part about the sun on the tail lights is not BS. It does have a line lock....so technically you called it sorta right..

Thanks for your encouragement. I'll post some more when I get them on the puter!

 

LOL- glad you're a sport about it. Awesome truck none-the-less.

 

That a sweet lookin truck

 

12 seconds on slicks, or street tires, if its street tires, what will it do on slicks???

cool dude i would love more pics of interior. i want to see this spedo and mabey u could write us a tech article on how to do it . this sounds like something i want to try. (little 85 spedo is lame)

 

Sweet lookin' truck you got there! I bet that thing gets some second looks from the ricers in your area.

 

Wow man awesome looking truck that thing must light up those tires heh very cool truck is a beauty man

 

i want to see the mustang gt gauges!

 

How to do it!

Soon as I get my stupid digital camera to recognize the media I will post pictures of the Mustang GT 140MPH speedometer.

It is a very easy transplant.

You remove the 140MPH from the Mustang cluster pod, remove the indicator needle, for both speedometers once they are out on the workbench.

Notes: This will only work with the OEM F-Series with the tripset option speedometer. The tripset button from the donor Mustang GT pod must be in the same relationship as the F-Series truck (there were two types in the 80's)
Some are a direct fit, while others had an offset trip button that will not work.

The guts will unbolt from the back of each speedometer face. You will be left with two speedometer faces. The guts from the GT I used, had the mounting points on opposite corners so I took the entire guts apart and put them into the OEM F-Series housing as opposed to gluing the guts to the back of the speedometer housing. Due to the extreme conditions, vibration, and sudden launch at the track I felt that no amount of glue could hold up over time.

I used a paper cutter to trim the 140MPH speedometer face (flat stock) to fit just inside the OEM F-Series speedometer face. The OEM F-Series speedometer face is somewhat concave while the GT face is flat. One inside the other works just right. The odometer cutout, tripset cutout, and button will line up perfectly with the OEM F-Series speedometer face. At this point you have a 140MPH overlay that looks cool but non-functional. Now to make it work right.

You will need to put a very slight preload on the speedometer during needle reassembly. This means that at rest, the spring must have about 1/32 reverse rotation before the needle is installed. This will keep the needle from bouncing at low speed. For my application I used the OEM F-Series pointer needle so all the gauges would match.

It took me several attempts to get the preload just right because the needle would either not work with no preload or bounce like crazy with too much preload. I used an electric drill to rotate the speedometer from zero to 20 MPH and zero to 60 MPH just as a check for needle bounce.

Mile marker to mile marker on the freeway the speed and odometer is right on. I had an assistant operate the digital (clock) timer so that 60MPH speed in one minute could be checked for accuracy. The speed and odometer are calibrated by the gear in the C6 transmission. Finding the correct gear took a lot of math homework and some help from Ford Racing to match gears in stock, with my tire/rim/gear ratio. Since the 1982 F-Series never came from the factory with 17" rims, 3.80/1 gears, and the fact my size tire was not invented then, a little math was involved to find the right gear, so knowing what they had in stock was a great help.

 

Chuckle....the first thing they notice is the deep resonating big block rumble and stumbling idle when I pull up to a stop light. Their little fartcan exhaust is immediately drowned out when the light turns green. Heck, I have more torque on my lug nuts than they can master at full RPM...

 

12 Seconds on slicks. I never made a run on street tires. Sorry!
