New Build Advice Needed

So, my son and I are doing a new build after putting together my old 69 Dart 440 car. Wanting to do turbo fuel injection project.
Looking for 250-300 hp
Heading to Mopar Nationals next week and looking for “stuff” and knowledge for the build.
Car : 1964 Dart Convertible
Block - 2806830-7 1714 BH
(Obviously not original)
Transmission 904 push button. Want to keep with adapter ring for late model snout.
- would really like convertor recommendations -
We will go through transmission.

Rear end - just finished narrowed 8 3/4 489 case with 3:23 gear and mini tub. New XHD leaf springs. Shocks not purchased

Front end - Qa1 upper and lower control arms and strut rods. Hotchkiss street shocks

Brakes 4 wheel disc.

given the set up what would YOU do to this 225 slant 6 for

Rods?
Pistons?
Wrist Pins?
Cam?
Convertor?
Valves?
Springs?
Turbo?
Fuel Injection system?
Intake?
Exhaust?

I’m an old guy that only thought these belonged in trucks. After coming back 30 years later I’m amazed at what’s out there to make these sing.

Any input greatly appreciated.

Thank you.
