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

How about stroke it with Scat 4.00 inch forged crank then supercharge it! 65'
