While tripping merrily through the mail, JERRY ROBERTS was overheard
 PH>         How big of an engine could you put in a 66 plymouth valiant?
 PH> Right now it has a slanted 6.....
 JR> Many moons ago, 1965,  I had a Dodge Dart GTS (a red-headed step child
 JR> of the Valiant) and it came with a 273 cu in. 235 horsepower right from
 JR> the show-room floor. It was a screamer, I remember in my younger days I
 JR> use to go looking for the Chevy 283's and Ford 289's. It was sleeper to
 JR> end all sleepers. 
 JR> There are probably others ie; 318 cu in that would fit also..
A Man after my own heart :-)  (I had a '64 GT ragtop, biggest engine you
could get then was a 225 slant.)  
At one time we did some measuring, and determined a 318 would have probably
bolted right in.  In '66 I believe the 318 was actually available as an 
option.
