intake and carb sugistions

I've never had any luck with 800 or 850 Holley's.
I took a 800 off my 10 second street car,well it was a 11 second street car untill I put my 750 on it and it went 10.70's.

I just finished my 512 ci.for my Charger and Put a 750 on it,No stumble or bog.
It has a .550 hyd cam.


Without knowing more about your comboThere's no way to give a recomendation.
