DeTomaso Mailing List: October 99, Message #185

The carb I have is  Holley 0-80508S. It's listed at the Holley site as a 4160 
750cfm if anyone wants to see more about it. I suggest you click the "product 
line" then "part number index", then "part listing." This will give you the 
fastest list of numbers. The sheet that came with it says it should not be 
used with adapters on spread-bore manifolds since adapters may have an 
adverse affect on cylinder-to-cylinder distribution. It's 50 state emission 
legal for 65 - 69 V8s. I guess if you put it on a Pantera - you'll go to 
jail!! It's a dual center feed, with electric choke and vacuum secondaries. I 
have what they call a "quick change secondary diaphragm kit", part no. 20-59. 
This allows you to change the secondary diaphragm springs without removing 
and disassembling the secondary housing. The springs are different colors for 
different "opening rates." Mine has the stock springs. It's at the parts 
places for about $270. It's in the same series as the 600cfm which is single 
feed and about $220. Hope this is some help.
