Mark Sullens converted my 950HP. Runs like a top, I only needed 1 jet change and 1 air bleed change to get it spot on!!

Heaths kits look good also, but from what Ive read you really need to change boosters also. If you have the tools to do it yourself, great. If not Id send my carb to either Mark or Heath and have them convert it for you.

Either way, Id skip QF and go with somebody who is more on a "grass roots" level with E85.
