best carburetor for chevy performance 290 hp 350

[JAM1777]

I have a 1969 Chevy C10 longbed, and i was at the auto store and someone said it sound nice....what do you have in it. ....and I told him it was a chevy performance 290 hp 350 crate. And he looked at the carb and told me it was a 400 four barrel holly and he said that he has had alot of problems with that carb and suggested that i change it to an edelbrock 600........im still learning about my truck but i know the people on this site have been a huge help!! So any advice or suggestions would be appreciated thanks
