Converted gas engines, due to the structural limitations of blocks etc, run 
at much lower compression than a true "virgin diesel" would...  The Olds 
350 diesel runs 16.5:1 I believe, while a true normally aspirated "virgin" 
diesel engine would run 22:1.  Turbocharged diesels run 17:1 to 19:1 
depending on what boost levels they anticipate and the conditions they are 
designed for.
