5.7 engine build

I am contemplating this swap and think I have came up with this.

5.7 hemi
stock heads ported
comp 268 cam
stock internals
fast self tuning with carb style intake
This would be over 500hp or am I dead wrong?

I also came up with needing
flexplate for 727
headers prob tti
motor mounts - i found mancini's but does some one make a solid mount
and oil pan

are these facts pretty accurate or am I lost
