MSD 7 AL 2 plus ???
 

Our stocker has a bug,?? Test the car it ran 10.80 @ 122 1.40 60' ran good, next pass car acts super lazy, car runs 11.50 @ 114 1..50 60'.
Battery checks good! Swapped coils, swapped carbs, timing is good, compression is good,
Has anyone had any issues with the 7 AL 2 plus, car don't miss fire at all, checked all I can check besides starting to replace parts, any thoughts are appreciated at this point. MIght add I replaces Trans an coverter as well but problem still exists, an unfortunately this car don't have a data recorder.

If you are running an MSD distributor it could be the magnetic pick-up. They are notorious for causing lost E.T. and the car doesn't miss a beat.

Hello Jim
Had similar problem ,the box need rebuilt.
Sent it to Pat Collins phone 704 995 4286 Mid West Tech.
Car pick up .60. Cost $150. Plus he suggest different coil $100.
Cheap fix for all the trips to race track trying to fix.
Good Luck

Ya I'm close to agreement on the box, it's definitely a key source right now. Thanks for the imput.

If that box has the little black timing chips in it, make sure they are all working. We damn near tore apart our whole car at Cecil a few years back and it was a zero timing chip that had lost continuity.
