alot of it depends on the specific parts involved, but you can find a shortblock for somewhere around 4k usually.
But parts add up.
heads
cam
pushrods
lifters
gaskets
bolts
injectors, etc...

244/250 .612/.613 112lsa
All in all i'm happy with it so far, it feels so much different than my old motor, night and day.

I had a 408 with stock heads (budget in mind at the time) and i still had fun with it everytime I mashed that loud pedal.
511rwhp might be about the highest dynoing Patriot heads I've seen, no need to swap those out. 
Looks awesome, definatly suprise some people who think it's just another ole' mulletwagon.

Hell, I figure i'm young and I might as well do it now.
You may pick up some inexpensive ponies by swapping your 75mm MAF to an 85mm version. With a 90mm TB, your MAF is now the choke point of your intake. Nice numbers by the way.

So I guess I can upgrade the both of those next and I am waiting for those LG headers for the f-body's to come out.
Hightempsilicone.com or Intakehoses.com both sell cool stuff you could use as a coupler.
