MSD Distributor
I have a MSD-8366 billet distributor on my 502 mag mpi, just bought it in March, well looks like my ign. module is bad as I am not getting any timing advance. I have called around to locate one and the module is part number 84665. My question is since I can't locate one locally, does it have to be an MSD module or are the AcDelco ones the same?

It isn't a mechanical advance, it is a 502 mag mpi (forgot to say it was an mpi in original post). The ignition module communicates with the ecu which in turn the ecu communicates with the module to tell the distributor when to fire. So if the module or/pick up, has a magnetic pick up, goes bad it can just lock it self at a set advance. It's all electrical.
I went ahead and ordered one from summit which will be here tomorrow, and I have spoken to MSD considering I just got this distributor March 30th and it only has 35hrs on it they gave me a RA number to send the faulty module in to be replaced with a new one.

I have seen a few of the same MSD units with bad ignition modules right out of the box. They solder the wires going to the pick up. The could be overheating the module when they solder the terminals. Or, It's from Happy Red China!

thats for the EST dist, and yes the advance curve is set in the module and the marine ones are usually different form the auto ones, and also MSD has been terrible the last few years on these, magnectic pickups etc failing...and yes they are outsourced from china...nuff said...MSD=may soon die
