As said alot of complaints on the 750 eddy. live every 24 hour block of time like it's your last day on earth

I have ridden around in it and it doesn't cough, hesitate, or do anything irritating. It also runs hard enough to pop the glovebox door open and curl the floormats backwards when you stand on it. I think either would work, but if your engine is fairly built then the bigger 800 version is the way to go. Last edited by Neil; 02/12/10 09:47 PM.

They all run good when properly tuned. We can have the same agument about tires, gas, oil the color of the sky. Either CFM will work well if tuned correctly. Buy what ever brand your more familiar with to make tuning it easier for you.

He has tried an 800 and 850 and went no faster so he ended up going back to the 750 which has run 11.40's in his mild 400 Dart. If you like the Eddy carbs I would agree the 800 Thunder series seem to be better from what I hear. Both the Holley and Eddy carbs can work good as it just boils down to which you care for and have good results with. Ron

A holley is a much better carb and for what you have I think you'd be much hapier w/ a holley. Any car is going to need tuning. Holley have much more to play with so I guess that's why some people don't like them. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

What year? 4 speed or auto? some 440 B's had 3 holleys What came on the car was not always the best performing carb for the application, only what was cheap at the time.

I have the Eddy 750 and it's a dog The 800 Eddy did run good on my buddies 408 small block but it seemed small..then he tunnel rammed it. It runs like a bat outta he// now
