Well, that one has sure seen happier days. The Roadmaster is the nicest one, biggest engine and a lot of them (not this one it seems) were equipped with Dynaflow. To put this one right would cost a fortune. I had a 46 Super in much better shape and it would have cost a fortune to do right, this thing is way far gone compared to that. These cars are not cheap to redo unless you do all the work yourself. The advantage here is that the engine (320 cu in) has precision insert bearings and if it was an automatic, would have hydraulic lifters. It's slightly cheaper to rebuild than the 248 with it's slush-cast bearings and shims is.
