Most accurate site for muscle car weights
 

As I said in the ZL-1 Vette thread, we re looking at running some races for muscle cars. So looking to know where is the most accurate weights for all makes that we can look up and maybe use as guidelines for each car?

We do not want a '69 BB Nova to have to weight as much as a '69 Chevelle or Impala. There was a reason why some cars were better "streetfighters" than others. Like M-code '69 Darts too.

Thanks in advance, John

Most but not all. They use Curb weight which means all fluids installed and a full tank of gas

Here is an example" 1969 Z/28

Thanks Lee. I was looking at that site once you posted it in the Nova thread.

Sounds like a neat deal! Just be prepared to listen to the whining about the rules and have thick skin. Long time racer here and let me tell you be firm and fair.

Look in the stock car classification guide area for shipping weights.

Years ago we would use the NADA Guide to get the cars shipping weight.

Thanks guys. Maybe get all 3 and take an average of 4sp weights for that car. NOt trying to figure each and every possible combo, but say a '69 BB Camaro, it would be based of BB 4 sp and that is it's weight.

Not going to be many rules. Actually pretty simple.

1. Weight for that car (example '69 BB Nova 4sp must weigh say 3300 lbs)
2. Must run OEM steel wheel, like a GM Rally wheel. Max 15" diameter.
3. Must run dual plane intake. Weight break for OEM dual plane.
4. No power adders of any kind, Nitrous, turbo, supercharger or nitro.

Tires were looking at up to 275/60R15 or 9" slick by sidewall designation.

The intake will take a lot of things out of play. Heads, carb engine size etc. You can only get so much through the dual plane intakes, it won't matter if it's a 706 or SR20 heads. You can port the intake, but not move the ports around pass where a gasket match will be the rule to a know standard.

This is going to be some executions, like if there isn't a readily available dual plane for that engine, and where to put "special" cars like ZL-1's. Stock style repop rims and intakes are cheap and we feel it's better for the class. EFI like FiTech/Sniper will be allowed, but not port injection with fuel rail conversions.

Find AMA Spec sheets. You can find a couple here:
