402 stroker forced induction questions

I have a 73 dart/swinger with a 402 stroker that has 9.5:1 compression. I been having issues with the holley 650 double pumper and have been contemplating installing a holley sniper self tuning efi kit then possibly a blow through turbo. My questions are is this possible and worth it or is there another route one might recommend. For instance maybe a roots style blower with carbs?? I'm just trying to get a little more power out of it. Thank you in advance for any help given
