Does anyone here have any experience, good or bad, with monoleaf suspension?

My '70 Nova has mono leaf rear solid axle... family owned car since
new. The leafs have sagged down to the point of not much spring
travel.  Year One advises replacing it with the 4 or 5 leaf

jobs, I'm going with 5.

@ 1965Windsor361: It has a 383 with a too rich Holley that no one seems to get up and running normally (has been refurbished twice and four people tried to set it up normally).
@ firedome: are those mono leafs original from the seventies then? My leafs are brand new so I hope they will last as long as that ;) I was concerned a bit about the safety, probably a bit overconcerned.

Maybe you should try a competition AFB from Edelbrock it seems to be great out of the box..  I run the old AVS and it seems to run the plug just right and I have the 383 Magnum cam in my 361.

Also.. I would love to see the mono-leaf installed... I really need new springs in the back of my Windsor and I would love to see all of the options before buying springs.

for $400 US you can get springs made by my guy.  Alcanspring.com in Colorado.  Man knows what he is doing.
 
Single leaves had a tendency of wheel hop and spring wrap.  They did them on the nova because it was light and cheap.  The typical Nova and equal cars with 6 Cylinder had a single leaf.  The V8 GM's had multi leaf.
 
We talked about this a few months ago.

Allright, since I already have the mono leafs I will try them out and if they really suck I know what to get 8) thanks!

Ya - my '70 Nova has the original factory mono-leaf springs - 250cu in
6 cyl.  Corvettes also had mono leafs some years, so couldn't be
too bad!!

My biggest issue with mono leaf is increased axle wrap.  Don't like it, don't want it.  I had a 69 Camaro that had a monoleaf, it wasn't the preferred setup.
Just my opinion though, like anything else, someone else will ove it for some reason.

It's been a while since I visited here and I am now in the phase of placing new suspension parts and am seriously doubting if I should go on with the Calvert Monoleafs w/o the link setup on a street car... I have read lots of stories about the possible hazard of the system failing - no stories of real failure just warnings...
So maybe I will just buy stock heavy duty springs after all... Bummer that I already have the monoleafs on stock though but safety is important too.

I'd go with multi-leaf.  That's what I'm doing on the Nova. Much less chance of sag over time.

I concur.  I gave you a link above to Alcan.  Inexpensive and great product.

For my wife's 81 Z28 I simply went to the spring shop (truck suspension, axles, leaf springs), and had them add one heavy spring with a little more arch than what is stock right now. It definitely fixed the rear extend-a-shackle need, and was a lot less than a full set.
 
As far as the carb goes, power valve itself has probably been blown. If the carb backfires too many times, it ruptures the diaphram and makes them dribble gas heavily. Running it that rich all the time is going to be bad, and granted you are changing fuel, this may save a whole lot of time and money in swapping over. If you do the power vavle, measure your vacuum, divide by two and add two and you will have the proper size, so for example, if it is 12inches of vacuum, then it is 6 plus 2, so an 8.5 power valve. If the valve is OK, jet size two numbers too big can be 4-5mpg difference.

For the carb I am currently refurbishing a Carter BBD 2bbl 1,1/2" with a cast iron intake.


When the 2bbl is on the car the Torker will be fitted a 425 IMPCO gas 'carb' and then the real driving will begin.

As I cannot edit my post a short follow-up:
I probably will buy heavy duty mopar springs (as I am in Europe this will be cheaper, easier and faster to do than to custombuild suspension overseas - shipping costs will be very high and as there are no planes I will have to wait a few weeks for the boat).

Anecdotally, it seems like a lot of folks have problems with those
particular Holleys... probably a good move. Also - gas in the oil...
have you checked your mechanical fuel pump diaphragm?

Sorry, I like Holley carbs, never a major problem like this with one, which is why I asked about the power valve. Since there are several different Holley carbs, which number do you have? You may also have a sunk float, which is hard to detect sometimes.

The fuel pump will be replaced as well :) I don't know the carb #, my car is 35 miles from here so I can't check right now.
