I need a known, good working, mechanical secondary 750. Looking for a 4150 or equivalant.

Let me know what you know about!

 

I have an original GM #3923289-DZ, Holley LIST 4053, date code - 992 (2nd week of September, 1969). 780CFM, Dual line, single pump. Been in storage for 5 years, nothing is froze up, but needs a full rebuild. Ask $425, negotiable.
