Damn...
You would think Don and I are partners and not competitor's!
I agree with absolutely everything he has said. Have I told you, Don makes all my rebuilt/custom motors?
He is so right about the power band too! You may think you are still pulling power, "it is not"! Once you go over the torque band you are wasting time! This is the hardest thing I had to learn on the drag strip. I absolutley knew the car was still pulling all the way to the rev limiter--6,800+ rpm.
Dyno showed us the max torque was right around 5,500. Do you know how hard it is to force a shift 1,500 rpm short when the nose is still in the air and your helmet is kissing the back of the seat!?
I mean, I have to actually force myself to shift, my hand, my butt, my brain says "not yet-not yet!" My times slips and speed say, "Told ya so!"
I've actually turned my tach in the dash so that the 6,000 rpm mark is straight up at twelve o:colock.
If you can get "her" on a dyno, it will be worth every penny of it. Take a Holley and an edelbrock with ya. Run at least two runs, then make up your own mind.
