440 and 727 for sale on marketplace

Again, I'm totally new to mopar. So what do you guys think of the 6.4 426 hemi short blocks from a2speed.com? Come with 11:1 compression? Throw a dual carb intake and a set of victor jr cnc heads on it? What kind of power do you think it would make? Also. My mopar has the stock inner fender wells and v8 frame.
Would that work with a hemi?
