How would you build a low 10’s street car

Cope has the $$$$ numbers pretty close to right...will probably cost more (5k ish if I had to guess).

Making a low 10 second power plant is not too hard, but making it street friendly too can be tough. My 67 Barracuda is a low 10 second street car, naturally aspirated 408 on e85. I drive it on the street quite a bit and race a lot. It is not the most street friendly car, but I don't mind it.

Building a turbo car would probably be cheaper than building an NA car; however, both will need the same safety parts, built trans, good converter, good suspension, good tires, good brakes (often overlooked), frame connectors, cage, etc.
