I'm looking at buying this truck. From the title it says it's a 1956 Chevy 6400. The VIN #V6B56S024625. I don't know all the lingo used to classify these things. I want to know what size it is (2ton?), and if I'm wasting my time starting a project with this truck. Its in good shape. Runs and drives fine. One owner truck. I'm wanting to bag it and do a diesel swap. Preferably Cummins. Any input would help.
