Supercharged or stroked 340

Got a 340 block getting prepped for a new build I had a 412 in in mind but. Then I considered standard stroke scat crank 6.123. Scat rods 30 cc dish pistons which would give about 8.3 compression ratio. Heads edelbrock Victors with a 671 supercharger. Our estimates are 500hp without 671 and 650 hp approx supercharged
Your input would be appreciated thanks
