My orginal MSO shows a delivery weight of 2685 with spare and fuel..... I have had my 71 Grabber weighed on NHRA's certified scales and with me, 7gallons of fuel, 6pt rollbar, full interior,no exhaust,no spare,9", and Torque Thrust II's.... I came in @ 2780 lbs........ MERRY CHRISTMAS EVERYONE!!!!!!!!!!!!!!!! http://mustangsandmore.50megs.com/MembersPics/S_TeasGrabber_1.jpg
Weight Ok those scales that go under each wheel are neet, you can balance all 4 corners if you like. Any way, Here is the scoop I have know Idea how much fuel is in the car but its under 8 gallons since that is how much I put in it from empty the last time I raced, So my 1972 (straigh 5 car originally) Maverick with a ALuminum head 302 with headers a victor jr intake holley carb original radiator, water pump, fan and so on, a c4 8" converter and a 9" with a light weight spool. full flowmaster exhaust, traction bars, full interior with Pinto buckets , a nos kit with a full 10 pound bottle. Two holley blue pumps, 15x3.5 welds up front and 15x8' sin the back with mt et streets 28x12.5's, a single battery in the trunck. a 6al box with a multi step retard. Fiberglass bumpers and a full one piece areo scoop fiberglass hood, FUll carpet and a Quarter stick shifter. and the car weighted 2410 so with me it would be 2630 so the scale at the city dump was off 145 pounds but either way 2600 is a very light car / wet with driver. Not the 2485 that I stated earlier but not that far off either, But for someone out there that has a maverick that weighs 3010 without a driver is very weird in my book but as I found in the article that I found each year and I mean every year the weight went up and by 1976 they were 2900+ !!!!

did you guys know that the early cars are lighter than the later (73-77) cars? I had a chance to compare two identical 2-door 6 cylinder mavs at a grave yard....one was a 70, the other a 76. The 76 had MUCH more gusseting in the roof area, firewall, rocker boxes, and numerous other areas. Also, on LDO cars, the glass is thicker, at least the windshield is anyway. My '74 street car has a really thick windshield, I would guess its probably 5-10 lbs heavier than most others I've seen. BTW, the '75 Bracket car (before cutting) went 2660 w/6-point cage and pretty much nothing else. That was with a 351w/powerglide/9" rear...the rear brake drums were the ones from an old Torino, 11" diameter, each drum weighs about 25 lbs, backing plates another 10lbs or so, then the 31 spline axles...etc etc. So far, I would guess a 100 lb weight loss just in the rear half of the car alone. I also noticed the other night when removing the front suspension that the factory drum brakes are extremely heavy. Just the drums/spindles for both sides outweigh the complete M2 crossmember with everything on it, including calipers and rotors. I would never have believed that the factory front drums were that heavy!
The NHRA brake point is ANY closed car running quicker then 11.99 and convertibles running quicker then 13.99 must have a roll bar. 10.99 or 135 MPH or quicker/faster requires a cage in everything. These are 1/4 mile times. As Far as weight, In '73 they had to add side protection(door guard beams) and that started the heavier crash bumpers and associated bracing. The '74 and later bumpers alone added a couple hundred pounds not including the structure needed to mount them. In '75 you add the cat converter and heavier exhaust. Oh and disc brakes are heavier then Drums and Drums aint light! When I used to run SCCA, we ran our sports cars with drums and velvetouch linings and save 20 lbs over the same car with disc brakes. 69.5-72 were most likely the lightest Mavs made.
i have a 71 grabber, 302, c-4, 9" rear. weld wheels all around, (15x3.5 up front) discs up front, no rear seat, 2 racing buckets, no rugs, 5 gallon fuel cell, no heater, non a/c car, no power steering. weighed it at the track on the scales they use for nhra divisional races. it also dosen't have a roll bar or frame connectors. came up 2850. since then i've added the us body aero hood, but put a second battery in the trunk. so i guess that offsets the hood. i can't see any way to get it down to 2450 without major modifications.:confused:
How do you take a 1971 maverick that fully loaded with a v8 a spare tire steel wheels ac ps disc brakes and bucket seats that left the factory (according to many articles that I have found and one guys shipping invoice from 1971) at 2670 and make it 2800 pounds, its not possible, Mine is a 72 it weighed 2700 when It left the factory and I removed 300+ from it just by going to aluminum heads wheels and glass hood and bumpers so 2400 is easy for a car that started at 2700
I wouldn't take any Ford published specification as gospel, especially from the 70's. Any other article you read is most likely just quoting the factory specs. Only way is to fairly certain is to check it on at least 2 or 3 different certified scales.
Weight Don Graham, If you read some of my posts from the begining of this topic you can see how dropping 300 pounds is not that hard, wheels, headers, aluminum intake and heads, plus bumpers and a hood drop these cars into the low 2500 pound range without any problem at all, especially the 70, 71, and 72, Shit the heaviest 70produced was only 2510 by 72 they had gained 200 pounds but 200 isnt hard to drop either, I may have been a fool to trust the scale at the city dump, but when I weighed it last friday on the digital 4 wheel scale I was convinced, I hear of mavericks all the times with mild set ups running deep into the 10's, this is due soley to their weight , according to some of the power speed programs, and the moroso power speed slide calculator at a race weight of 2700 pounds it only takes just over 400 rwhp to put a car into the 10's Make that car 3100 pounds and its now 500+ hp to do the same thing. Go figure Dave
My Comet is a 74 GT, I replaced the BIG bumpers with skinny ones (fiberglass bumper in the rear), fiberglass lift off hood, fiberglass leaf springs (lost alot with those), aluminum cylinder heads, aluminum radiator, lightweight motor accessories, replaced doors with doors from a 71 maverick(no beams inside the doors), aluminum driveshaft, Bogart Racing Rims (lightest wheels made!) Kirkey aluminum racing seats up front, full interior,6-point roll cage and the 9" added some weight. The car weighs 2675 without the driver, add 200 lbs. for the driver puts it to 2875. I have 125lbs. of lead in the trunk to get me to the REQUIRED class weight of 3000lb. and about 35lbs more for gas. That's the weight breakdown on my car!!!
yea, but I thought everyone had decided that the reason they were heavier was because of the big bumpers and side impact beams. Mine has neither of those. I know the front bumper assembly I took off weighed at least 100 lbs., I could barely pick up the damn thing by myself. My car doesn't have any accessories except an aluminum alternator and an aluminum water pump. I got rid of the rear drums and put the lightweight Aerospace disk brake kit.....where is the extra weight coming from????? something doesn't add up??
Weight I agree your about 200 fat, unless the year to year wight gain is due to something other than what is obvious, Remember that the weight continued to go up every year even after they had big bumpers, but your 74 doesnt fit into that catagory, but you do have a 150 pound roll bar that I dont have, but you have fiberglass leafs that I am missing, I stand by the original math that I performed on my car. Wich is simple it rolled out at 2700 and I removed 300pounds with heads wheels intake headers glass hood and bumpers along with a 8" converter wich amazingly weighs 20 pounds less than a 12", I did add a 9" but used a light weight spool, your guess is as good as mine, :bananaman :bananaman :bananaman :bananaman :bananaman :bananaman :bananaman
My whole car is fiberglass except the roof the quarters and bumpers (1971 comet). All the windows are lexan except the front . Back halfed car . Weld wheels , iron heads , 7 gallon tank , fiberglass buckets , no interior , 6 point roll bar . The last time I weighed it at a NHRA track it was 2450 with a full tank and no driver I forgot ..... that was with no signal lights and headlight which it has a again now so I would guess around 2500 . When I first took my car there it was stock except for the wheels and it weighed 2925 .
Weight Wheelbase 2-Door 103.0 Curb Weight 2-Door 2681 LB Curb Weight 2-Door 2736 LB (Grabber) these are ford published articles for 1971 in their statment this is max shipping weight based on all available options, How you end up 200 pounds heavier when you first weighed your car is beyond me. Note that this includes a full size spair, a radio, floor mats, trunk mat, a jack (and they werent light) auto, v8 powersteering and ac if it were avail in that year, Maybe comets because of the big front end nose picked up some weight cus I cant find the varience any place else!
you've definitely got me thinking again. i see that a 71 grabber should weigh about 2588. i stripped most of the interior, got rid of the gas tank, aluminum radiator, lost a bunch of brackets. headers with only dynomax bullet mufflers bolted to them and a few other reductions. i think i'm going to have to reweigh it next time at the track. maybe i read the scales wrong? won't be til next month but i'll let you know what i find out. this is interesting.
