Car not running what is should, need help.

Your header's are 1 5/8 which I went 11.29 with and had a full exhaust on the car. I did step up to TTI's. You don't need them to run 12 sec quarter's.

I agree with Billy on the ign, get that junk Mopar conversion stuff off. I had ton's of problem's with that stuff. The MSD isn't that expensive. Now that alone will not gain a second but it's a start.

The 2 1/4 exhaust isn't helping either, if you don't want the expense of new exhaust throw some dumps on or just uncork it.

Do you know any tranny guy's that can diagnose what your feeling? Maybe something in there is draining your power.???? I'm no tranny expert so I can't help there. Have you checked your timing to make sure your getting full advance?
