Supercharged or stroked 340

IRISH RT said
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

After great Discussions with My Engine Builder and after doing all the Calculations , Supercharging with a 671 makes sense, Next Question is which block 340 or 360 because he can achieve the same in either block, might be a waste using a rare 340 ?? and the 360 has bigger main journals
