When to shift?

Chassis dyno. What's that cost? Half the parts in the motor? $500.
I test practically at the track, even if it takes me all summer. I don't trust the speed shop dudes, they are chebby boys. It would be stressful for me to turn over the keys. And besides they never know much about Mopars.
I guess doing all it by myself, is the fun of it.
Reaction times win the race in the brackets. I have run 16 a second Cougar and won first a place trophy.
