    Went and looked at an AC cab today for my plow truck. I'm planning on putting my 90 454 from my ex cab dually in it.

    any luck with World Products or Dart heads?

    I've got a friend who is trying to talk me into trading a set of World Products 200cfm small block cast iron heads. By my research, it looks like they're probably Sportsman IIs, but there us a chance that they're Dart Iron Eagle 200s as well. I'll actually be looking to build a mild small...

    Where the best blast media to use to remove paint and plastic body filler from a truck without damaging the metal underneath? I've got a long road ahead of me with my 77 and thought that perhaps blasting it first would be a good start. Of course before blasting the cab, the doors would be...
