thinking out loud here, but a 347 with a relatively mild cam and 9:1 - 9.5:1 or so probably won't be all that "doggy" out of boost .. a 350 horse 347 can be done with a pretty mild setup that should be very streetable. Add 14-15 pounds of boost or so and assuming everything was sized right for 350 horse, it's got potential to be a 700 hp animal.
