For your application, you don't need a forged crank. You won't be spinning it that high, or putting that much of a load on it. That will save some dough.
Here's an excellent rotating assembly for $1,700. Pay the extra $200 for balancing, it's worth it.

My 427 stroker made over 500 dyno proven rwhp on out of the box Dart 195 heads. The torque curve was about as flat as a table top from about 2,500 to redline. They are an excellent product, with a lot of bang for the buck. Other heads will make more peak HP, but you'll give up low end torque. Low end torque is what you want in a street car.
Comp cams makes some excellent off the shelf cams depending on the intake system you plan on using. I highly recommend EFI. I don't own anything with a carb.
