boosted or normally aspirated will both need good gizards to live.The boost can take an engine and make 1.2 to 1.5 times as much power as normally aspirated.
so if you built a 396/383 making 1.25 horse power per cube,then the bosted version would make1.75 hp/cube or more.
do some math to see what you want Vs what you can afford. what ever you bolt that into will need premium suspension/tires/brakes and trans/diff.
If you put 675 plus hp in a stock car,something will break everytime you get into the throttle
