so ever since i converted my 400 big block to a 4bbl with a edelbrock thunder series (offroad one) its had a sputter bogging issue. so i ended up blowing a fuel pump which replaced didnt sputter as bad then changed the fuel filter and way better but it still does it sometimes not as bad tho its hard to explain the sound. but just talking to my people at work and around they think it has something to do with the carb and reading up on these carbs theres tones of issues like that and i did everything i could that they said for me to do besides taking it apart and rebuilding it(which i dont think im qualified for) so what is the best out of box carb that would be perfect for 4x4ing

 

what size is it 750,650.600
