What is a good asking price for a Dz 302 probbably will need to be rebuilt it was running?

 

Prices are all over the map,also depends on what year and how complete and what options as they're not all the same.
Some had angle plug heads for instance,some had the dual quad crossram intake,an original 1967 is very rare so worth a lot as only a couple hundred were made.
eBay has a few listed. https://www.ebay.com/sch/i.html?_fro...ne&_sacat=6028

 

A 302 CID in '67 &'68 would be engine code MO; '69 is DZ.
Certainly would be a screamer if one were to use moly rings, std volume oil pump, 6-inch balancer, and an alum flywheel.
