Pair (2) Holley 780 Cfm Mechanical Secondary Like Center Squirters) Tunnel Ram on 2040-parts.com

  Here we have a pair of Holley list # 3310-1, 780 cfm squarebore, 4 barrel, mechanical secondary carburetors professionally remanufactured and set up for street and strip use. These carbs have been converted from vacuum to mechanical secondary and are ideal for use on a tunnel ram mounted inline or sideways. I've installed the old-school 4-way squirter and 1:1 racing secondary link. They employ new teflon coated throttle shafts, modern universal linkage, downleg boosters, milled choke horns for added flow and enhanced booster signal, and the baseplates have been resurfaced for a perfect seal. They will flow 820+ cfm each and will easily support 1000-1200 horsepower as a pair. THESE ARE NOT FOR MILD STREET ENGINES OR CRUISING, they are intended for use on well-built, large displacement, big blocks. They are best used for racing and occasional trips to the local car cruise. These are very similar to the 660 or 850 center squirter carbs from the late 60's that were popular in racing and Pro-Street applications. Also, these carbs do NOT have vacuum ports, although most engines that would need 1640+ cfm would have no use for a vacuum port! Please call the number below with any questions or concerns regarding your application.  

      Each has been assembled with high-flow .110" needle & seat assemblies, 50cc pump, # 28/31 (.028" front, .031" rear), FOUR-WAY squirter, and vent baffles. The jetting is 73 up front with a 4.5" Hg high-flow power valve, and the #21 rear metering plate was modified to be slightly richer than stock. They were assembled with new screws, jets, blue non-stick gaskets, and the mounting gaskets are included as shown.  

     Please email or call me at my shop with any questions regarding fitment. I'll need your engine, trans (stall if automatic), and rear gear specs. I can be reached at 724-523-2947 from 9 am 'til 7 pm, eastern standard time. 

    I welcome all potential bidders to check my feedback. My feedback from carburetor sales is 100%, and I've sold hundreds in the past few years. I am the owner/operator of a one-man shop and my carbs are built with pride one at a time. Please see my other auctions for more great deals.

      Thanks, Steve
