Nice looking 455 jatty. It looks HUGE sitting on top of that hill! I see you have a pretty steep grade there! I am running a 455 with HDAPs, six suitcase weights and wheel weights. I am runnig 23" tires on the rear. I am using a blower. I haven't had alot of snow yet, but I was able to blow snow on a very steep driveway without chains. This was the last storm, about 6" and no ice. I plan on using chains only when its absolutely necessary.
