Ben,
It's all a matter of balance between our desires, our pocketbooks, and perhaps a dash of practicality. Just for your consideration, the following combination gives 351 HP at 5300 RPM and 402 ft/lb of torque at 3400 RPM. The torque curve is quite flat, at 390+ ft/lb from 2500 to 4400 RPM.
351W block bored .030
9.5 to 1 compression
GT40P iron heads
Comp Cams XE274H cam (.519/.523 lift)
Performer manifold (for hood clearance without a scoop)
Edelbrock 600 CFM carburetor
MSD 6AL ignition
I'm wasn't looking for the ultimate in engines but I anticipate that the resulting 7.5 lb per horsepower will still let me get into more trouble with this car than I need. By the way, the sound at idle of this combination is extremely nice.
The complete turnkey engine, dyno test, warranty and all, ran about $4500.
