I finally went to the track to try out the stroker with the tunnel ram. Car was running about .7 off my last outing and seemed flat on the top end. Only did 2 passes and best was a 12.2 at around 110 mph. (last time out was doing 11.5 at 120 ish. Anyway, I had checked my timing before my first run and to my suprise, it showed to be way off, like 10 degrees after tdc at idle! I rolled the dist around to 12 btdc and locked it down. Reved it up and the mechanical advance took it to 35 ish so seemed to be working right. I then proceeded to make my 2 passes and with my poor results, I checked the timing again. My dist had not moved, but it was showing ot be way off again like before. I called it quits for the night and came home. I have not had much time to mess with it, but I did try another timing light to rule out that. I think maybe my balancer may be slipping and thus throwing the mark off. Short of that, would have to be an issue inside my Mallory Unilite dizzy or maybe an MSD box issue. Will pull a plug and rotate #1 to the top tonight and look at the the balancer mark. If that proves good, anybody got any other ideas? I do not have vacuum advance hooked up, so that is out of the equation.
Thanks
