68 Barracuda fastback tube chassis build

That would be pretty awesome. I’m hoping for 5.90s which I think is pretty achievable given how light the car is. But whatever it runs it runs. Just want it to be consistent, and reliable. Dial it, and run it.
I assumed 2750 at the line, losing 50lbs from lighter heads and block, plus a 200lb driver and fuel. Assuming a 700 hp engine, those are the numbers Wallace gives out. But we all know there's LOTS of variables.
