Stock 383's were 15 second cars most days. Well set up with some slicks and gears, and they improved some.
In any case I think you should put a fuel pressure gauge on the six pack car and run it. Also maybe a vacuum gauge. The vacuum gauge may show a valve spring issue, etc.
The times do clearly show that the motor has torque, but not hp.
