Drop the air pressure down in the tires makes a big difference in the snow I also have a 383 power wagon with a 727 iPhone with automatic you can get more wheel speed in the snow
Yeah I know it doesn’t look like it but there is only 15psi in them I can run them down to 5 pounds but I was driving down the highway right after and 15 is as low as I’ll run them on the road. And yeah my blazer is an auto and definitely gets around better in snow foresure with an automatic
