I cut my teeth on hot rodding and street racing with a 1955 Chrysler 331 C.I. New Yorker motor in a customized 1933 Ford Pickup with the early Ford drive train in it
I ended up buying a 1957 Chrysler 300C hardtop as a family car several years later as well as buying every Chrysler Fire Power 1955 to 1958 hemi motor I could buy
That was a long time ago, your motor doesn't look like what I remember those motors looking like out of the cars, is it a De Soto or Dodge?
If not one of them what year and brand is it?
