I was using an 30+ year old - my trusty Craftsman- sears chrome timing light on a new motor with MSD 6AL old version. the timing seemed to keep retarding - so keep advancing.

Then blew a head gasket and damaged block on a NEW motor.

A racer friend got the flaming river to work with the MSD and also on his race car - bought one and worked for a couple years.

Could the new Firecore wires make it hard to read the signal?

I could do the craftsman again with a trustworthy part #?

Thanks for all you guys help.
