Think about guys running vac advance, which gives an additional amount of advance to the mechanical. At cruising rpm/speed, these guys are seeing WAY more than what you would see.

Well we changed the springs and ended up with full advance around 2800rpm. We were able to put about 20 miles on the car and I woud say everything we did was an improvement to the car. We pulled it to 7000rpm and in my opinion about 6000rpm you get the oh sh** feeling. 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"
