Does anyone know the real weight of a 66 442 sport coupe [Post] ? My registration says 3167, is that possible, that seems real light.. JOE will probably know this I bet.

 

NHRA stock class guides show 3452 lbs for a 442 based on the F85 Club Coupe and 3503 lbs for a 442 based on the Cutlass Sport Coupe. The difference is rubber floor mats vs. carpet, sound deadening, etc.

By the way, NHRA lists a 1966 F85 club coupe with V6 and manual trans at 2950 lbs.

 

I believe some variance might be attributed to the type of "registration" you're referring to i.e. vehicle title agency, county, state vehicle tax assessment authority, etc. I've found discrepancies in not only (curb) weight but in vehicle identification, as well. The "agency" might have simply pooled vehicles together for "registration" purposes. I've found lots of discrepancies in vehicle registration parameters over the various states I've resided.

 

INTERESTING ,,,Thanks again JOE. I knew you would know that !!! I like what the reg says better however

 

You are probably are correct on that,,Thanks Norm to you as well.!!!

 

Curb weight, shipping weight, and NHRA race weight are three different vehicle configurations with different amounts of gasoline and other things.

 

And, which configuration to use can be a toss of the coin by the CBU entering the data.

 

Find a grainery, truck dock, or travel center with a scale. Drive your car over the scale to get an exact weight. Takes the guesswork out.

 

Weighed my 66 f85 2Dr post coup, mid 70s 455, iron intake, manual steering and brakes,1/4 tank of gas. 3560lb.

 

Or your local landfill. They usually charge by the (minimal) pound and will have a scale you drive across upon entering and again upon leaving.

 

When I had my 66 f85 post,( sbo, t56, no carpet) it was 3650ish. My 67 4 door hardtop weighed in at 3440ish.

 

This is a good idea, however I probably will not like the outcome of the numbers....maybe I will have the fenders acid dipped !!

 

NOS front fender weighs about 28 lb.

 

i can visualize you with one of your fenders hanging off a Fish scale

 

Don’t acid dip that beautiful fender! Take the ballast weight out of the hole in it 😁

 

I didn't have to weigh the fender--I took the weight off the GMPD box and subtracted one pound. I did weigh a lot of other stuff back in the 1970s.

 

X 2
As I recall, cars always weighed 100-200 pounds more than shipping weight. I would assume that the "curb weight" was used by car magazines and was from weighing at a public scale..

 

It is very simple to find somewhere to weigh your car if you are anywhere near a big city.

 

I'm curious to know what you'll do with the weight information if you elect to weigh your car or find it varies from the registration weight of 3167?

 

It may also be a fat fingered typo.

 

It’s a fallacy that a post car is a bunch lighter than a hardtop.

the factory base weights are just base weights. the base weight of a post F85 is with a 6cyl. It would come with manual steering, manual brakes and manual trans.

if equipped with the same drive train, what is the weight difference?

 

The NHRA weights I posted account for drivetrain. All of the numbers I posted are for 442s with the 400 motor and manual trans, except for the V6 car for info. They list lower numbers for different drivetrains in the same body.
You are correct that the differences between post cars and hardtops is negligible - typically in the 30-40 lb range. Most of that is due to differences in sound deadening and window mechanisms, not the actual body. The exterior body panels are all the same, and there is very little difference in the internal structural supports.

 

Whatever the actual weight is, it’s probably more than you want, and more than expected

 

So why the question in the first place? Is it really about the taxes? Go weigh it. Super super super simple to weigh a car. Do It!!

 

I was more curious then anything else, The reg weight just seemed very low to me.

 

just curious is all , the reg seemed way low. I know it is per,,, all the post I got.

 

Question time. I’m still looking for the elusive “no sound deadening” or “insulation” on the F85’s…where did this come from ? Does it say delete that stuff in the GM manuals ?

I’ve parted out a few F85’s that were bare bones 6 cyl cars and doing another one now. this is a deluxe F85 and just like all the others..it has deadening in the roof, under the dash/firewall and floor had that brown wool type stuff.

 

Joe should know what the story is

 

I wish I had a definitive answer. The Product Assembly Manual doesn't include the stuff that Fisher Body installed. I think part of it was the lack of jute backing under rubber floor mats vs. under carpet. I do know that for 1966 the PIM shows that the under-hood insulation pad was only used on the 3500-3600 (F85 Deluxe) and 3800 (Cutlass) model lines, not on the 3100-3200 F85 models.

 

I don’t know if this car came with carpet or rubber mats. there were only some pieces of the jute still on the floor. Being a deluxe I would think carpet.

i have a bares bones 69 F85 post 6 cyl car. Bench seat radio delete std steering and brakes. It had rubber with jute under it..remember tearing it out. I can’t remember if it has roof deadening or not…I’m gonna check..and I’ll check under the hood.

what’s funny about the 69 F85 flat hood, is it’s got an under skin that has very few cut outs or holes in it like the Cutlass hood. So even if it has no under hood insulation, which don’t weigh anything, it looks like it would be heavier?

 

Yeah, carpet was standard equipment in the Deluxe models.

It's like on the 70 W-30 cars that claimed "reduced sound deadening" that was simply deleting the hood insulation that couldn't be used with the O.A.I. hood anyway (and ignoring the fact that the fiberglass hood weighs more than the metal one).

 

Yep....the glass hood is quite a bit heavier. The springs to hold it open are different. Guys learn that real quick after they install one with stock hood springs and it comes down on their head😂😂

didn’t Olds say the hood was lite weight fibreglass in their marketing?
