I converted my carb to e85 with a kit off ebay from Rob Mix. It had metering blocks, gaskets, squirters, and jets for a baseline. I also put in a Holley black pump, 1/2 fuel line, steel mesh fuel filter (paper filters no worky)....but the most important part in my opinion is a wideband so you can tune it. e85 burns so clean it is almost impossible to read a plug. I just picked up a cheap wideband on Summit that was about $150, works great. I think I only spent about $650 total to convert...but that was a few years ago.
