Here's a link to a pretty capable crate engine builder:
Roush engines 2yr/24kwarr!If thats the way you wanna go. I have nothing bad to say about crate motors. I bought one back in 1990 and it's still running 10.50s at 125mph with just an intake & cam swap. Never been apart. Best $3495 I ever spent.
Don't start cutting corners on your new engine you haven't even started to build yet! Better to spent a little more money & time now than to have to do this again. It's not like this is something you have to do once a month. Remember, this time around it will be YOUR motor.
If you need to learn the advantages of a Stroker engine call (631)226-2234 ask for Lee. He'll bring you up speed.
