HEI conversion benefits

70 Duster,
Post #9. I hope you did NOT use dielectric grease!!!! That is an insulating grease & has poor heat transfer properties, the opposite of what is needed. You need heat transfer compound between the module & the heat sink.

Another thing to be aware of: the Mopar elec dist does NOT need to be grounded to work.

If you elect to use the set up in post #5 [ elegant, simple & all you need], the dist body needs to be grounded; dist body carries the high 5.5 amp coil current. Roughen the mounting feet on the dist clamp to ensure a good connection.
