How would you build a low 10’s street car

A lot of great information coming from this thread and I think I’ve come to my conclusion of what’s going to happen, it seems regardless of how I want to reach my goals it’s going to take minimum 10-15k to do it, I think I might go for a new engine and pick up a gen 3 hemi down the line and run twins, for now I think making in the ballpark of 450hp with the 340 would be a real fun car, the car is pretty quick as it is it’s kept up with a 2019 camaro with the LT1, plans would be build the 340 have fun with it for a bit then sell the 340 to fund the twin hemi build
sense you already have the 340 etc you could always build a 416 out of the 340 and add boost to it. Also there is a guy on Mozart's that has a green 62 plymouth 4 door, that built a magnum base 360 with a single turbo that runs in the 9 in the 1/4 and is fully treatable.
