383 or 350 stroker?
http://www.cadillacforums.com/forums
If so they are the same thing, a stroked 350 is 99% of the time stroked to a 383 via a SBC 400 crank(3.75" as compared to the 350's 3.48 stroke).There are also kits to stroke a 350 to a 396 not as common as the added expense is usually not worth the 13cubic inches.
I'm also a member on cadillac forums and it seems as if there not as well versed over there on engine and engine related questions.
