How would you build a low 10’s street car

I’ve got a 68 340 barracuda with a 4 speed and 3.55 rear gear it’s got a cam just a touch above stock and x heads, also got an LD340 intake with carter 1406 afb carb basically a stock rig but also have the hi-po exhaust manifolds, I want to get this car into the 10’s and still be streetable, how would you guys go about this? I eventually may want to turn the car into a daily so if mpgs can be kept in mind with the aforementioned goal that would be a plus. I was thinking something along the line of turbos, overdrive and 2.91’s but I’m just spitballing and have no real knowledge of mechanics behind me

Good luck doing that yourself, especially starting with what you have. It would be easier, and probably cheaper, it just go buy a new Hellcat. The 2021 version will run mid 10's. 2021 Dodge Challenger SRT Super Stock Runs 10.5 Bone Stock Right Off The Dealer’s Lot!
