I live in a large metro area (Minneaplois) so E85 is everywhere but I dont want to regulate my trips around town based on where I can buy 110. If E85 is not an option, which I hear mixed reviews about, and I would need to change pistons and heads then its not worth doing anything to it. Id sell it and build another. ??????
If u have a document, then what's a pn# for the pistons? If u cant find it, bare minum pull a valve cover and get a casting number, if your looking at buying heads anyways, screw it, pull a head and see what you have.
