Projects 57 Plymouth Plaza Engine question

I bought this 56 plaza the guy says it has a "stock" 318cc engine, but as I was going thru specs all I see that these cars had were 277 or 303's in'ems, could this be a special option in 57' the 318?

thanks

The car in the photo attached to your thread is a '56 Plymouth.

 

Like the man sez, that's a '56. Nice car. The Plaza probably has a 277 "A" engine, good reliable power.

 

Some info on "A" engine sizes, there were 277, 301, 303, 313, 318 and 326 cubic inch versions. The 318 wasn't available in your Pilgrim, but it could have been swapped in later.
