update
A BIG thanks to Craig and Lance at fast for sending me there MSD-4 box to try it and yes it worked. I made the race. the new HO box was not anygood either. So MSD sent me there tester to test the boxes on the car but there's is nothing like caspers. there's hook's up to there box and it shows that it was working but with the casper's unit going thru the module then the dis and back to the coil it would not work.So all the MSD tester's and new boxes are going back again!! Lance is going to look at my stuff for me and MSD is looking at the lot numbers on the back off the MSD Dis4 boxes to see what may have been changed over the years. The only thing I could come up with is my first box and Lance's first box was very old and they worked.
If anyone has time and would like to help If you have a Dis4 or A Dis4HO that is working to 8000rpm's right the lot number on a post here and maybe this will help them fix this problem. It is on the back of the unit on a little sticker.
thanks richie
