46 on a 3.6

If you have original Webers I can help you.Do to your port size you should use the original jetting with one change.Change the main jets to 180 with the 42mm venturis.They are just a little smaller than the 3.6 ports.MAIN jet is always 4 times the size of the venture plus 5% for a larger motor.I have a few sets of 42mm if you need them.I have a nice set of custom step stainless headers and muffler if you need another 25-30 HP.Ciao Fred
