can 10:1 compression 408 get in 10`s

Tens shouldn't be a problem with your combo, looks like a good one to me. I don't think you could keep this one 'out' of the ten second bracket. And if it doesn't run the number...question would be 'why is it so slow?' But I think you will be happy with the results there 73Dart. Please keep us all informed as to your progress. Good luck, Terry.
