What carb is the best for the ds. I have a alba pipe and am geting the rev box. I want more responce and top speed.

 

I am bias toward the Edelbrock.

 

I like the HSR series 42MM Mikuni flat slide for a motor such as yours. The 45MM is too much for a mild motor, so don't let yourself get talked into that, especially if your looking for throttle responce. I haven't tested the Edlebrock yet, but if they wanted to send me one, I could do multiple unit testing on it, on the dyno and/or in the field.
