My Wife won't drive hers in the snow either.
72 Dart Swinger 318/904
The trans was rebuilt right before we bought it off Craigslist 2 blocks from our house, and it had a wiped cam on what looked like a fresh .030 over rebuild.
I put a 68 340 grind cam in it with all new MP lifters, new oil pump and all new bearings and it runs great.
Completely stock except for the gauge cluster and new Pioneer blue tooth stereo I got her for her birthday. (dash was already cut for a modern stereo)
Man, I gotta get that tire swapped to the inside.LOL
