Wow, lots of discussion about the 427 stroker!

Tom basically asks, is that a reasonable price?

In my opinion, there is not enough data there to tell.
What components were used?  Yes it has aluminium heads, but
it doesn't say what kind, or if any work has been done to them.
Doesn't mention main stud girdles, valve train stud girdles,
Doesn't say who built it, or what kind of reputation they have.  
(I'm sorry, anyone can write Expertly blueprinted.  I've seen
a *lot* of variations in "expert" abilities)
Doesn't have a dyno sheet with it.  Doesn't mention a redline, 
carb prep, baffling in the oil pan,  or a *lot* of other factors that 
go into making an engine (and affect the cost!).
I'd guess, that there would be average quality parts in
that motor for that price, and that the motor would stand
up to light track use, if appropriatly rev-limited. (5700-6000)
Pure conjecture on my part.

Dave's point seems to be that by buying the parts, and assembling
it yourself, you can build a "427W" for under 5K.     PAW sells
a kit for 3000$ (cast iron heads), so yes, if you're willing to do
a lot of the work, and don't "charge yourself" for the time, it's
certainly possible to make an engine with those listed specs for under 5K.
How long the motor lasts, is somewhat a function of how much time
you take, your apptitude for noticing potential problems, and
depending on experience, some portion of luck!, and of course
(as Dave pointed out) your use!! :)   

Gary's point seems to be that if you purchase such a beast from a
reputable builder, that certainly could be a reasonable price.  
Depending on components and the builder, that could well be a bargain!
It is certainly possible to spend 9K in parts alone to make a 427W.
How much reliability do you need/want for the 500+ HP?  That will probably
dictate the price.

Also, someone else mentioned "the rest" of the Windsor story.
Yes, the motor does "bolt in" and fits rather well in the
engine bay.  Headers, and some bracketry work are needed, as well
as a special hose for the thermostat housing. (or a custom housing).
So there are some additional costs to consider.  Rob McMullens web

site details a conversion (and even the cost) to a Windsor motor.
