best racing ign system.

i raced in the same class and never had a failure with the gm system but the Chrysler system needs extra wires and ballast resistor , and i had coil failure several times with oil cooled coils most people dont under stand a dirt track is like off road racing lotts of bumps that shake everything loose
Oil cooled coils should not be used in such applications and never mounted sideways. The solid core coils should be used. Many guys complain when they mounted there coil to the OE location on there MoPar at at they would fail. And they should fail because there instructions, at least the ones I have read state to mount them up and down standing up. The solid coils can be mounted in an OEM location.

This was not directed at you and I have to make a disclaimer that I don’t race circle track. Just street cars and drag cars.
