Sometimes you luck out, more often you don't, but with an overbore, new pistons, and a performance cam to go along with the Edelbrock 573 tri power intake manifold, this just may end up being the engine for my wife Rose Marie's Crown Victoria.
Canadian produced Y-Block engines in both Ford, Monarch, Mercury and Meteor cars produced during the '50s are all identified by a two letter block suffix code and four or five character engine serial number stamped on the front of the engine just below the left cylinder head up by the valley pan.
The suffix codes are as follows:
1955 - SQ or SR or SS = 272 cu. in. ST = 292 cu. in.
1956 - TQ = 272 cu. in. TT or TTD = 292 cu. in. TV or TVD = 312 cu. in.
1957 - VG or VQ = 272 cu. in. VT or VTD = 292 cu. in. VV or VVD = 312 cu. in.
1958 - WQ = 272 cu. in. WTD = 292 cu. in.
1959 - YTD = 292 cu. in.
Hope this helps you in your search for the elusive Y, and Happy Hunting!
