what are the main differences between a 302 and a boss 302

 

i think alot of it is in the heads, and the compression.. other than that,

$$$$

 

heads, cam, CR, Intake

 

Yup and a 4 bolt block with screw in freeze plugs and a steel crank with the shorter 289 rod that is beefier.

 

The online Ford 25th Anniversary issue parts catalogue,goes into great depth,about each motor...from 289cid and up.There are comparison tables and part#'s if you require them.All your detailed questions can be explained .
