330 hemi?

I wasnt sure if anyone knew anything about these, but there is a 330 desoto hemi 1956 for 400$ near me and i wasnt sure if it would be worth looking into. also, i didnt know where to put this either, since its old, i thought id put it in the early section. i was curious if it would work in a abody drive train or rough mpg estimate or anything like that, i couldnt find much about them so i thought id ask here.
