If you have a 2-series differential ratio with a radical cam, you'll get no power at the low end. How does it pull at high rpms?Jack

How many times are you going to ask this question?
Right now I count 10 threads (including this one) asking the same questions...

Do you want one of us to come down and fix the damn car for you?
I pretty much told you what your problem is here:

As well as a couple of other folks in different threads.
This is getting very old so either take the advice and fix the car or sell it...

My Response:
Your cam is too radical for the rear gears. Big cams have no low end torque, and a 2-series gear puts a big load on the engine before you get up on the power curve.
You have the wrong gears for your cam. No matter how many times you ask the question, the answer is the same.Jack

Being rude has nothing to do with it and I'm not mad... Just trying to make a point. Like Jack said, asking the same question 10 times or a hundred isn't going to change the answer so quit wasting bandwidth...
