Can anyone tell me spring OD, wire diameter, and coil count for the GM 7036019 power piston spring? 

Thanks!

Save me the time to do a Google search.  Is that the spring used in the 7029207, 7040204/205 and many other GM high performance applications?  If that's the spring you are referring to it's the orange spring in my kit.

I have all the specs since I have them made in the USA by a spring winding company and currently have about 18,000 in stock if you need one.......

No... this would be the 8"-4" spring used in 7029202 and a lot of other lower performance applications.  I have an assortment of springs from various carb projects, and I am trying to figure out which one is a 7036019.  Thanks!

The #7036019 power piston spring is used in every 1969 Chevy Passenger Quadrajet.
12 coils, .204" O.D. and .0155" wire diameter.

I finally got around to measuring my orange PP spring.  It's almost exactly the same specs as given above.  Wire diameter .016", 12 coils if you count the ends, and just a tad over 1" long.  I used the 7029207 spring as a sample when I started having them made 20 years ago.  Currently over 2000 of them in stock.  I sell a lot of the orange springs to other vendors, very popular part......
