Default Unitized to HEI ignition conversion
I plan to upgrade my '72 455 from the original Unitized ignition to an HEI unit. Are the HEI's 'plug-and-play' for this type of conversion?

I've found the instructions to change from points and coil to HEI, but nothing on Unitized to HEI.

TIA for any help you can give.
