Everyone with that carb on a Roush has trouble with hesitation. I had the same problem with my 427 srtw. We played with the 770 street avenger for a long time trying to solve the problem. Got better but always had a hesitation. I would recommend using the 770 as paper weight and buy a 750 or 850 cfm holley 4150hp double pumper. Make sure to get it without the choke, it is for sissies. It was well worth the 900$ to me. Zero hesitation, very smooth. Should also be good for a few ponies.
