Yes ,
mine picked up over a BG825 mighty demon,20+RWHP. But street driving the 825 was nicer when cold , cleared the cold stumble off idle earlier .
I have , like you , put it down to big carb/venturi on a single plane intake . Was the same with a M1 and the current Victor .
A friends 440 with a 1050 Dom is similar . You can hear when pulling away cold there is a stumble till it gets a bit more air speed - fine when warm .
Keep with it ,Patrick said to me next carb will be a Dominator
