I would like to know what is better to switch the 307 engine too.

I have heard the 403 olds, 350 olds, or the ever loving 455
what is the easiest to switch too and do all the components of the 307 match up(ac,power steering) etc

307, 350, and 403 are the same block essentially and are fairly easily interchanged. 455s have a higher deck so it's a bit harder but it could be worth it for the extra inches.
