I just watched an e85 conversion get done on a sbc 355 and it was freaking amaizing. total castiron engine for a bomber class race car make as muchpower with the e85 as the 110 at 350 hp and 426 ft lbs at 5300 rpm. after about 10 mins of runnig you could reach down and hold the sides of the heads and they were moderately warm. my grand prix is performance oriented so im not worried about the loss of mpgs as my build would probably need to run 104 anyways at like 6 dollars a gallon. Im running about 9.8 compression and wanting to stick with my 3.4 pulley no intercooler. I can get a conversion kit for around 300 dollars and am wanting others opinions. So far all the things ive seen have impressed me very much. i know everyone knocks e85 cause its taking corn out of the mouths of starving pickle pickers but we cantely on foreign oil forever. if you can make more hp for less money and keep the money in america why the hell not. i never considered doing this till about 3 days ago and have been doing some reading and from what i seen on that sbc i was very very impressed and for me thats not aneasy task.
