DaveW, or anyone,
So what is the preferred PCM, the '7427 with the $E6 or $OD mask?
, or the '8625 which appears newer?
Or is there not enough difference between them to be concerned about for a basic reliable unit, with a possibility of add-ons later such as cam and Vortec heads.
Right now just learning to make the truck reliable and have a learning platform.
Thanks,
Louis
