Echlin is a division/brand of NAPA/Echlin and that part # is an ignition module (by the looks of the part #).

would that be the 'transistor switch' part of the distributor, similar to the black plastic lump found in the older HEI distributors by any chance ??
where would it live in a LT1 ?
I'm just curious to know what they actually changed,
Thanks again

Possibly. Go on Echlin's website and have a look. Or ask the shop that did the work to explain it to you.
They charged you, they should explain what they did and why :).
