Hey gang!

For my stock 440, would you recommend an Edelbrock or Holley carburetor? Also, what CFM should I look for?

Personal call, but in the early 70's, a 600 cfm Holley was a popular option on 440s from the factory.

I like Holleys, but a lot may depend on your plans for the car, so little more info might help.

I am playing around with a 68 slightly souped up 440, and the 750 and 800 cfm Ederblock AFB's are not working right. Not rich enough at WOT, and/or too rich at part load, trying to get it riech enough at WOT. But you have a stock cam and low compression ratio, so that type of carburetor might work for you. The advantage of the AFB's is that they are reliable and low cost, and tend to give you good mpg.


BTW, in the late 60's the regular 440 came with some sort of a holley. These OEM holleys got a terrible reputation for leaks. You may want to stay away from an OEM holley. That does not apply for the aftermarket versions, I expect they solved these issues.

 

The factory holleys were junk because the overheated and warped NO insulator between the carb and intake

 

Thank you all very much. I appreciate the help end quick replies. For now, I'm gonna keep the motor stock. So with your information, I think I'm gonna go with a 600 CFM Edelbrock.

 

Yuck, go Holley I have used the factory Holley on a sbf and it worked great! 600 Holley was to small, 750 vac secondary is what you need, then a tune!
