Get the SNSC mod here  -  http://www.designsbyrioux.net/page3.html

Make a copy of the folder and rename it to SNSC70_GNS.

Rename SNSC70.dat to SNSC70_GNS.dat

Change all the files that need changing to change the physics to GNS from CTS - http://www.thepits.us/files/tutorials/thepits_n2003_newmod1.pdf  (unzip this zip into the newly created SNSC70_GNS folder)
Change the cars from .cts to .gns using the car converter -  http://www.masgrafx.com/masgrafxracing/modules.php?op=modload&name=Downloads&file=index&req=viewsdownload&sid=19

Once you get the physics converted, change the chassis to 1 on the track you want to run to drop the HP (plate chassis is 1).  You will also want to change the sound pack you are using to something more high pitched (red line is around 7000 RPMs).  I took my GN70 sounds and raised the pitch by 27% to get it to sound like a small block.

Have fun!
