I run a 406 in my “Track car”, 72 Olds Cutlass, and yes getting it out of the hole requires low end grunt. But, I run Drag Radials and have a suspension setup to take the hit, 1.57 60ft. Most "Daily drivers" would never be able to use the power I make down low. A normal suspension and radial street tire would just go up in smoke with the torque.
I could be wrong, but most "Daily Drivers" smash the gas when they are already rolling. A 350 with instant boost available from these SN units would feel mighty strong. Also, it would get decent mileage while driving normally.
In my opinion it's best to be realistic about how the vehicle is going to be used, and what can be afforded (read, broken parts replaced). It's easy to make power these days, but it's still expensive to up-grade an entire car to handle the power you can make. If you can afford a 500hp motor then make sure you can afford the parts to go along with it, axles, transmissions, suspension upgrades, larger fuel lines, etc. If you can't afford the other parts, then build a car you can enjoy without worrying about breaking it.
Yes, 383 kits are dirt cheap, and the added 30 cubic inches would be worth 40-50 ft/lbs of torque down low. But, gas isn't getting any cheaper. If it was a naturally aspirated engine then I agree go big, but with the blower there is no reason too. Look how fast all the 302-347 SBF's with blowers are. My buddy gets 20mpg on the way to the track and runs high 10's with 332 cu in SBF with mild tune and single digit boost.
Nice thing about a supercharger/nitrous is that you have the power when you want it, but don't have to feed it all the time.
Different strokes for different folks. Not saying I'm right or your wrong, just my opinion.
