I switched my car to E85 this season and have had very good success. I had mike at Avanti Performance set up an old school 850 DP and it works great. He machined off the choke horn, drilled and tapped for screw in air bleeds and did all needed mods and set it up on his test motor in house and it worked very well right out of the box. Total cost was just over $350. The carb was acid dipped and looks like a new one! check him out avantiperformaceproducts.com
