Holley 750 Carburetors

[Mike81K10]

I have noticed a very limited Holley 750 carburetors with Electric Choke and Vacuum Secondaries. In fact, I think they only have one if that. Some I have seen and like are mechanical secondary. Was wondering how others feel about the mechanical secondaries. Kinda like the Holley Ultra Double Pumper Carburetors 0-76750RD. I do not think mechanical secondaries are as proficient on the highway.

PS: What is the cfm of the Rochester carburetors. Was wondering if they are equivalent to the 750.

What do you have on there now? If you're sticking with carburetion, I'd look into a new Q-Jet https://www.summitracing.com/search/department/air-fuel-delivery/part-type/carburetors?SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=quadrajet

I agree 100% with the Q-Jet advice.  They are better carbs and more fuel efficient.  they are just harder to hotrod because parts arent as available and a lot of people dont know about them because they all junk the quadrajunks because they are factory...  they are excellent carbs.
