Stroke old 340 or new crate engine

I dare you to describe " poor" .. That car with 400 honest horsepower, should run 11's .. I call it ,good.
What a beautiful Duster....
Well maybe I was a little harsh. It did run real nice with great throttle response just not awesome performance. My last project was a CTS-v wagon 6 speed manual with 565hp at the tires. Maybe that's my problem
