Bolmida,
Yes that is a 7000 RPM chip.
So that tells us you have a MESD 6AL box. This is the same ignition box I had and I had very similar problems that were heat realted. If the box is in the engine compartment, move it to inside the car. I know it is a pain in the butt but it has to be done.
When you stated you "in it hard" Was this just before the pop? If so you may have peeked the chip and the MSD box shut down the power to the distributer. This most definantly will cause the problems you are describing.
The MSD is trying to do what you have ask it to do. By putting the 7000 RPM chip in the box you are asking the box to limit the revs the engine is allowed. Thus the 7000 chip. You have a few choices you should choose careully. You can either change the chip to a higher number 7500, 8000 or remove it all together. The box cam with several other chips. If you do not have the other contact MSD for replacements or take it out all together.
The MSD will work with no chip in it. It simply works like the MSD 6 box, the difference is the "AL" which indicates the automatic limiter.
If you re not sure the red line point on the car you should be VERY carefull remoeving the chip all together. I ran mine without one at all but I knew the limits of the engine, I never raced it.
Try that and let us know. Also as Wayne said do one thing at a time.
