If this seems a silly question.. excuse me.
What happens if/when a future owner doesn't know what it really is or is not and plugs a OEM module in its place ?
Nothing bad, it will go back to working the same as before it was replaced depending on the coil used.
With HEI the coil is the must have part, not the module.
If it had an HEI coil and they took that off, it probably wouldn't start due to the big plug gap that HEI allows.
I honestly don't think someone would by this and then forget about it. :D
