I'm very happy with the improvement but thats alot of RPM to get to before you feel like your actually in a fast car. With my current gearing we were knocking on 130mph at 7000rpm in in 3rd. I'm all for fast stuff but thats hauling butt on the street and I don't think thats something I want to do in the car everytime I go for a drive. Feels good to know the motor must be pretty solid still so lets continue on with this saga.
*Headers- jus as many people and articles on how big headers are better as there are that small headers are better. Up is down and down is up.
*Gearing- I believe I have the .82 TKO-600 and the car has 3:31's in it. Gearing has really been mentioned in this thread but I think this is something that could be overlooked. The first thought I have is that 3:73's would be a good move but I've read some interesting threads on 4:10's. The fastest I would cruise is 70mph but the majority of my driving is under 70mph.
*Camshaft-From what you have said this is a big culprit if not the biggest. Current dyno shows the motor peaking at 6600rpm. I like winding the motor out but with these gears and 7000rpm its a pretty good stretch and nothing feels like its happeniing until you are 5500-7000rpm "which is exaclty what you said the cam should be like"

The characteristics of your engine are what I look for with my own personal stuff. I like the higher revving pieces....
If I owned your car, I would stick a 4.10 gear in it and reap the benefits.
Otherwise, you'll have to make a decision on where you want the power to be and how you want to drive the car, then make it do what you want.
