I often wonder what my truck will be like in 40 years .... :lol: 40 year old electronics ought to perform wonderfully ... :rolleyes:

 

Nice Cutlass! I don't see to many mid 70's vehicles around here much, although recently they are coming out of the woodwork. 60's cars are becoming untouchable, so those and even 80's vehicles are starting to show up more than ever. Maybe I'd better hang on to my rusty '89 S10 Blazer ...

Took the CX5 while the stuff cures on the Tahoe. Haven't seen my wife so happy to drive since we sold the Vette. She is the opposite of a car person. Some cars transend that I guess...

I sure do remember those cars. I always liked the Can Am and the '73-'75 Hurst/Olds, the '74 Hurst/Olds and '76 Buick Regal Indy pace cars, among others. I think the collector market is just now beginning to barely recongnize cars from that era.

I've always thought smog killed them so much that the "all original" cars will never have the market pre 1971 cars have. But, then you'll see the occasional Smokey style TA sell for over 40k

Yeah that's what kept them from being very sought after all these years. Now with nothing affordable left, (and prices of those era cars rising too) people are digging them out of mothballs. Good thing is, all that crap can be jettisoned without too much effort. I can;t even tell you how many MILES of vacuum line I have hanging in the barn from that ...

It wasn't smog so much as it was gas mileage. The 73-77 cars sold in numbers that will never be seen again, since everybody bought American cars til later. The across -the- board redesigns in 1978 were just downright ugly, plus nobody wanted a downsized car anyway. Can you imagine "upgrading" from this:

Yeah that was a big part of it too. The cheapout years ... a never-ending saga it seems.

So true about the downsized models '78 and up. I do like the last gen Olds 442 ('86-'87) and Buick T-Type/GNX from same years, though.

I have had just a couple of 80's GM cars (out of 80+ classics)...an 84 Riv Convertible and an 86 GN. Horrible build quality...doors all rattle, thin sheet metal (w/o the engineering they have today to make them tight) . Disgraceful cars. The GN will run though...that's for sure.

Always loved that body from that era - the GN, Monte Carlo, Cutlass, Grand Prix, Regal.

 

I had an '85 Monte when it was 7 years old. Thing used to belch blue smoke at every light, and fog the road out when I took off. Took 20 seconds for second gear to slip slip slip in, and about the same length of time to get into reverse. Thing had hit everything but the lottery, but I used to take that thing everywhere! I could let go of the steering wheel on long right hand sweepers and it would steer right around it - my buddies used to laugh their asses off. Thing pulled to the right like you wouldn't believe. I took that thing to the mountains of NH, and rolled through NYC a couple times. Only left me stranded once in 3 years - right at an auto parts store with a bum starter, lol. What a gem that was! Still ran like a top though. As crappy as it was, it was one of the best cars I owned in those days.

All that will buff out.

 

LOL

Is that a large can of bondo sneaking up behind it?

HAHAHA! Hot water heater, with someone's lamp shade on top, lol. "Luxury apartments" there ... :lol:

 

Yeah we tried buffing it out .... with a BFH.

 

I just noticed the rear rims packed with snow, from blowing it out sideways every time I took a turn. :D

I installed 3 gauges in mine today. 2 Aeroforce and one boost gauge. Tomorrow or Wednesday stabilizer bars will be going in.

 

Now if I can figure out how to adjust the contrast on those first 2 that would be awesome lol....if you know how please reply to my thread about it.

    • hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you  
    • Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.
    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package. 
    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.
