I personally recommend Mark Sullens (DragChevette) on www.e85forum.com. His website is posted above.

Sometimes you get what you pay for. For a top notch carb conversion done right, look at all the parts Mr.Pbody posted. If a vendor isn't replacing all that, it isn't done all the way. You can make them run with less, but it won't get all the performance you could.

You should also consider just buying a new E85 carb. Eric68 on www.e85forum.com sells them. This way your good gasoline carb can either be reused, or sold to offset the cost of a new carb. A good running carb (on any fuel) is worth keeping or having another racer use.
