"Hello, I bought my wife a '55 Mayfair from a person in Canada. I've had trouble finding info for it because of its Canadian origin. From what I have found, it's actually a '55 Plymouth Belvedere that the Canadians slapped a Dodge front clip on and labeled a Dodge. The engine number starts with D59. I have not found anything on that, but I think it is a 260cid because of info I found on the vin number. If someone can give me any info regarding this beast, I would appreciate it, or a web site like this one that deals with Canadian Dodges such as mine... Mnay Thanx, Dave"
until 1956 Plymouth used Dodge engines, Dodge at the time had a 270 Hemi and a 270 Poly, 260 Poly was there also, but uncommon, I just found this on Allpar. so the '55 Plymododge Mayfair/ Belvedere would have a Dodge 270 Hemi or Poly, even tho it's really a plymo
