Few questions with regard to programming 101-Big Picture

[CSH-HQ]

Well just so happens, gm used the 1227749 in both the syclone (6cyl), and 
turbo sunbird (4cyl).  There is a hac/editor (java) available at the syty
site (syty at syty.com) or something similiar to that.  An archives search will 
get the URLs, if noone responds with them.  I'm working off of laptop, 
without all resources available.
