Thanks for that, but are the weight there legit? I'm looking at Sept 2017 results and has:

Tony Ragla 1969 Nova SS396/375Hp 4sp @ 3538
Victoria Waligora 1969 Camaro SS396/375 3A @ 3496

So the first time I have seen a similar option Camaro WITH AUTO (T400) being lighter than a Nova with a 4 sp.

That's the issue you run into when trying to compare published weights with actual scale weights. I'm not sure what to suggest for you when trying to put together a race class based on weights that are published. Without physically putting the cars on the scales they can be all over the place, giving some cars of same make and model a slight advantage if you try to put them in a certain weight class.

I have my bird setup to run pure stock but haven't made any attempt to lighten it. A 70 formula RAIII with PS and PDB, 400 turbo, as the only weight adding options. Scales at 3600 lbs. exactly without driver and a full tank of gas (spare removed), and that was on an NHRA cert scale just last month at the races. I'd be interested in seeing what a published weight for this car is if you have a source you've decided on?

I've scaled everything I own, just for my own purposes to compare times with others. I've been surprised at what some of these old muscle cars weigh.

Yep.

I didn't want to be a wet rag but I've been weighing '65 A bodies for 40 years and they are all over the place. Option content makes a huge difference and published weights are seemingly from a random number generator.

I would suggest the PSMCD data is the most real world info available.

Agree.

I scaled our 69 RS Z/28. RS adds some weight but I wouldn't think it would be a ton. I was surprised when it weighed 3472 lbs. That's with the spare in place and 3/4 tank of gas, no driver. Quite a bit heavier than I thought it would be, especially when people I talk to act like they are 3200 lbs cars. It's only 128 lbs lighter than my 70 bird, which is quite a bit bigger physically when you park them side by side.
My 72 SS 454 chevelle, PS and PDB, and factory AC scales 3,908 lbs, without the spare and a full tank of gas. 4,108 lbs. with me in it. I either need to quit eating cheese burgers or find some weight to take out of the car, lol.

Thanks Lee,

I had to go back and look at my notes on the bird because I've scaled it several times over the years. The car with it's optional rally II wheels installed scaled 3650 lbs. The 3600 I referred to was just last month at the track where I installed a set of aluminum wheels from another car to make some runs. Scaled the car right after the finish line and it was 3600 with 3/4 tank of gas, spare tire removed for these runs. That's the lightest the car has ever been. Over the years I have always raced the car with rallys, and with me in it the race weight hovers around 3850 give or take depending on how much gas is in it.

In this link, you can find the AMA Specifications for the 1969 Camaro from the GM Heritage Center:

https://www.gmheritagecenter.com/doc...let-Camaro.pdf

On page 55, it shows vehicle weights plus options. Curb weight with the V8 hardtop is 3135.

The Z28 package adds 83 lbs.
The Z22 RS package adds 27.
M20 adds 16, while the M21/M22 adds 4 (yes, both add 1/4 of what the M20 adds)
Front disc brakes add 26.

Following this page are the AMA specs. It shows the Z/28 as having a curb weight of 3296 lbs.
Same document shows front disc brakes adds 41, plus 11 for power.

So that gets back to what I've always seemed to find with my own cars, that the published weights always seem to be a bit on the light side.

Looking over the first set of stats you provide, the Z/28 package adds weight, which would include disc brakes. So one could assume you wouldn't add it twice as the stats might suggest. So ignoring the 26 lbs. and adding 83 lbs. for Z/28 and another 27 lbs. for the RS package we still only come up with 3245 lbs. Which is what I always hear people say. Not even close to what my RS Z weighs at 3472 lbs. Has power steering but I don't see that adding more than another 10-15 lbs.

Then look at the AMA specs and they more than double the disc brake weight. ??? Not sure what to believe since these cars, for me anyway, and being on an actual scale, always seem to swing all over the place.

Not trying to spoil the party and I hope EZ Nova finds a way to get these racing classes off the ground. Just pointing out what you might run into.
