Title: MSD box 6al going bad ? ...
Post by: 69kona on May 17, 2016, 06:24:30 AM
Well here we go. Got a cutting out at anything above 4500rpm . Removed rev limiter and still have problems
New wires and distributor
Fuel psi 7.5
There's a 8680 MSD dial retard in the set up too
How do I test it to se if it's the MSD box
Causing my problem?

You have to swap it with another to see.

This is why I run a racing HEI now. It works for my application, locked at 32 degrees.

Causing my problem?  Is this with the new motor?  I have a MSD box at home you could try it is a 6AL and you are welcome to it.
