Suggestions needed for a carb and convertor
90% Street with that combo??? Man, you got some stones meathead! I love it. :D:D:D
I know a member here "clinteg" is running a 8" 5000ish stall on his SB that he claims is very streetable down low. I don't remember who built it for him, but a search may be able to find it? Regardless, a custom built unit will be absolutely necessary to give you the street/track performance you'll need.
As far as the carb...What was used on the dyno?
