OP isn't against tuning, just isn't nearly as experienced at it as everyone here.
I'm not set on 750 CFM at all, if the board thinks that's clearly too small... no problem at all, I'm completely open to a larger one. That Street Demon does look pretty good though.
I guess I should have just asked what everyone thought the best carb is for a 440 stoker with Edelbrock performer intake, and 3.55 gears that gets mostly mild mannered driving with the occasional WOT (for someone with limited tuning experience, but totally open to it).
Again... I really appreciate the help.
