Default World's fastest Montego

So I decided to start a build thread here to document what I'm doing with my Montego GT.

For those who aren't familiar, here's a little background.....I found this car in 1996 sitting in a field behind a truck stop up in the mountains. It had been there for 14 years at the time and the weeds around it were as tall as the car. I saw the fastback roofline through the weeds and decided to take a closer look. After some negotiation with the truck stop owner, I had it towed to my house and attained title on it.

From what I've been able to gather, a woman was driving the car in the dead of winter when the radiator hose blew and she kept driving it until she arrived at the truck stop. After being given an estimate to repair the car, she never returned, so the car was parked out back and forgotten.

It was also around this time I started hearing about open road racing, where a stretch of public road 50-100 miles long is shut down for people to run at speeds that would result in felony charges under any other circumstances, so I decided to build the car to run in these events.

At this point, I've run two open road events which have been fun, but I decided to take a run at Bonneville this year to see what that is like.

The plan was to have a new engine ready for Bonneville, but as I'm sure most of you are familiar, family obligations came first so I'm going to run the factory installed D3 headed 429. This is the same engine that caused the car to be abandoned all those years ago. When I tore it down, I found two melted pistons, but everything else was fine. It still has the same block, crank, rods, heads and timing cover.

The thread title is a play on World's Fastest Indian, and because I've been seeing people call out their cars as fastest (insert make/model). My goals for the car are to have the world's fastest street legal 72/73 Montego GT. At this point, I don't know if anyone has been faster than my 132 mph run at the SORC, so I'm laying claim to being the fastest. Fastest meaning top speed, not 1/4 mile time. This time around at Bonneville we're running for the 150 club ( http://saltflats.com/I50_Club_2009.html ). Not sure if we have the power to run the number, being at 4800 ft out there, but we're going to have fun trying.

That is really cool Carl!! That road course looks like a BLAST!! Keep us informed with updates.

What kind of telemetry device are you using to get the extra info in the video?

2.75's are good gears for the flats if you have enough hp and low cd...the mile events are just a longer drag race..I'm currently running 4.10's which hopefully ,if we have actually gotten rid of all our bugs...will let me get over 200...Our favorite open road event is BBORR...59 miles each way..Run same gears..Favorite tires are now Michelan.pilot sport ps2's (Y) rated and stickier than the Hooiser R6's.. at least on my truck.. traction, torque transfer,and the friction load of the wind above 160mph are the only problems..especially if your driving a brick like us..lol rdw..

My father bought a '72 4dr Montego new, factory ordered. They are nice cars, although I like the '72 over the '73 since it does not have that rail road post 5mph bumper.

Over the years I've seen maybe 4 - 5 of fastback Montego GT's. For sure a rare car. Is one down here on CL, original '73 GT 429/auto. car for sale.

I use a Contour GPS camera that captures the GPS data, and Dashware video software.

I've been wanting to run the BBORR. Probably not this coming year, but maybe the year after. Tires are tricky with a big car like this. It's tough to find something with enough load rating, a high speed rating, and a big enough diameter.

Total production for the GT was 4464 units in 1973. There are 171 known to be in existence today. Of the 4464, 302 were big blocks....making it more rare than a Boss 429 Mustang. There are 12 known to exist today.

My road racer have had it up to 160 170 range was still pulling a bit but speedo needle hits the inside of the factory gage at one point and speedo goes a bit nuts after that. Strips someting out. Have run several SCCA autocrosses with good resuls untill I blew my rear trying to find redd line. Currently running 3.27 instead of the 3.55s I had. Going with 3.90s soon.
Front air dam from a mid 90s Chevy truck helped a lot. Also the trunk mounted lugage rack, removing the cross bar helped issues with high speed rear end lift.
Tires have also been a issue as the car weighs around 4000 lbs. BFG 275 50S ON THE FRONT AND 295 50 S ON THE REAR WERE GOOD (2050 load rating each).
They quit making the 275s. Went with BFG KDWS (with the flame tread) next285 30 by 18s front and 295 35s rear.
Load rating on these are 1605 front and 1705 rear. After a 2 years of running them they quit making the 285s. Everything I have found in that size for the front in around 1300 lbs load rating. Tried something in that range once and the tires would be going in the opposite direction the car was starting at low speeds.
Had trouble with bending wheels also.

Are you adding weight and running slicks for the flats? We had a sheet of 3/8 plate steel cut to fit in the bed back when running on dirt/salt..Tires are a problem..Have had to go up to 18's to get right weight / dia...on 315-30 frt.and 335-30 rears to get gearing right (.64 fifth) should put me at 7200rpm /211mph at 100 ft. from 1mile line....If I can get my timing problem fixed...rdw

Nope. Running on the same tires I'm driving there on. The 150 club is more of a "run what ya brung" deal. I think DOT speed rated tires are actually required.

I'd believe that. Every one I've seen personally have been 351's. Your GT and the one on CL down here are the only 429 cars I know of. I have not checked that one out on a CL, but is supposed to be a factory 429 car. Do you know if it is one of the 12 known to exist? Guess must be a registry for these cars?

There is a Montego GT registry, and most of us will try to get a VIN number on any that we see. I'm pretty sure I've seen that car before, so it's probably already in the registry. The guy that keeps track of everything doesn't publish a list of VIN's so it's hard to say for sure.

Carl, can you explain the 3rd video to me? Are you trying to maintain a certain average speed thru that course? If so, what speed? What is the deal with that bullseye looking guage at the top? Always thought that stuff would be cool to do.

You should know better than to have a street car that can break the speed limit, you should write yourself a ticket.

The round gauge is for G forces. As you can see, I played it very conservative in the turns not going much over .5G's. These races are not the place to push the limits of a car's handling. The road course on the other hand, you can go crazy. There's one turn there where I hit better than 1G which is pretty good for a 4600 pound dinosaur on street tires.

The idea with open road racing (in all classes except unlimited) is to average a certain speed over the length of the course. There are classes from 80 mph to 180 mph. Whoever comes closest to the average wins. In the unlimited class, the fastest car wins and they have no speed limit. For the non-unlimited classes, your top speed (or tech speed) is limited based on safety equipment and/or speed class. If they catch you speeding, you're disqualified. In the case of that video I was in the 90mph class with a tech speed of 120mph. It's surprisingly difficult and competitive. You need to have an average that's two or three decimals out to have a chance at placing. My northbound average was 90.004 mph which was good enough for 2nd place, but my southbound average of 89.722 which bumped me down to 9th place for the event.

What I learned in that event is that watching the speedo and controlling the car while doing 120 on a two lane chip seal shoulderless road with ditches on either side isn't easy. Next time I run up there, I plan to enter the 100mph class which has a 140mph tech speed so that I can pay more attention to the road.

My safety equipment qualifies me for 168mph at all the events except the SORC, which limits everyone to 140 because of the road conditions.

This guy set a world record last year for fastest car on a public road, averaging 217 mph with a top speed of 250+ (the radar guns don't read higher than 248.50 mph).

Did you have a "co-pilot/navigator"? Or solo?
