HEI in Mopar ECU casing

very cool and just think that gm module will live longer being away from all that heat inside the distributor lets keep this a secret Lol[/QUOTE

Heat yes, length no.

The GM module needs to be really close to the distributor, because of the drop thru a long wire.

Found this out on my engine start stand, I had all the wiring at the front of the engine, near where the radiator is, mounted the module at the front.
No fire. After checking all the wiring etc, and doing a little reading.

Moved the module to the back of the stand, actually bolting it on the back of the head of the motor.

Instant spark.

Keep the wiring short like under 2' from the distruibutor and you should be fine.
