I can do a complete rotating assembly, with a Scat crank, Scat rods, Probe pistons, rings, and bearings for around $1300.

The Edelbrock Performer RPM heads work well for a street build. Even with a 2.09" intake valve, we've got them to flow almost 350cfm. They would be a cheaper alternative to some of the high dollar heads.

Match it up with a good hydraulic roller camshaft, ditch the Torker intake in favor of a Victor 460 and you'll have your 650hp.

It will pull a fat lady of a tricycle!! I have a spare 460 block and have thought about a stuffing a long arm between the pan rails.What kind of clearancing is required to swing a combo like this,and how bad does it make the rod angle?
