mine seems to jump up after 1 min or so...My idle is at 1200 or so, i need to back it off some? In the video you car went 9.77 133 mph was it, looks like it hooks awesome....Rear tires were slicks right?
I have 493 i am running a dominatior 1050 also....The builder states that this is the best carb for this motor...12.2 COMP, 7OO lift roller, 10.0 1/4 1.35 60'...
