To avoid confusion, you mean holley gold box right?  If you had a Holley HEI
(uses HEI as a specific name) like the GM trucks have I doubt you'd have
removed it for a prestolite... the scout conversions for such module go for
$$$.  The HEI is the one with the coil inside the cap.

Is your white wire hooked up to the correct place?

Find anything that mentions years?  From the Binder Books description it
seems a little vauge about what is covered.
