Outer Limits 4x4 Board

A friend of mine fitted a 38 weber to his 79 3.5 rangie. Currently it has 155 main jets and 220 air jets fitted. He would like to know what the best jetting for this setup is and what fuel consumption should be like.

Thanks

The weber is not a popular conversion here so we probably wont be much help. Most guys here use a rochester or holley carb on conversions.

Regards,
Nick.
