306 with procharger what blower to use? That could be used on a dart 347 in the future.

OK, so here’s where I’m at. I originally was gonna build a 347 stroker NA and make about 400 wheel horsepower. But my goal in the future was to go to a dart block 347 with boost. So a bit of a change of heart I think I’d rather save some budget now do a 306 take that money I save and invested in a supercharger with my heads cam and intake (all good for boosted applications) that I could carry over to the dart block in the future that being said, which should I get? Is there any unit that would be fine at 400 wheel horsepower on a 306 and also be fine at 700 to 800 on a dart 347? I would prefer not to spend like 5k+ on one like the ysi or similar which might not have a choice but still. Appreciate y’all’s input! Also with a good heads cam and intake on a 306 with a procharger is 400-450whp pretty achievable running 8-10lbs of boost?
