What's the brand of carb got to do with fan blades coming off?

Anyway, I've run Edelburps and Holleys. Every Edelbrock carb I've had was nothing but trouble. I was told I could just setit and forget it. Well, for about 3 months(which is the warranty time) it was great, then they always tended to puke out on me, flood my engine alot, wouldn't idle right, ran rich and fouled plugs all the time. The final straw for me was when I was pulling into traffic and had to get on it to get up to speed when it choked the engine down and stalled on me in the middle of oncoming traffic. I bought a Holley that weekend. It's been a great carb with very little trouble. The carb I bought was a 570 Street Avenger. I'm still running the same carb on my engine now with a mild cam and it runs great.

I personally think your main problem is too much carb. 750cfm is way too much for any mild sb. 600cfm would be the max. The 850 Eddy you're looking at will cause you more problems later down the road. If your gonna get an Eddy carb, don't go any bigger than a 600

I'm not really gonna say that one brand is better than the other, but from my experiences, the Holley has worked better for me. The Holleys tend to get finicky while tuning, but once tuned right, their awsome carbs and you can get max. performance out of the Holley. The Eddys are good carbs for the guys who don't want to spend the time to tune a carb. That's why they seem to be more simple, but you will only be able to get decent performance compared to Holley.

IMO it's a trade-off. Either get decent perf. with little tinkering with the Eddys or tinker with a Holley some and get max. performance.
