I totally agree.Heads,cam etc.Was just looking for thoughts on HP/torque that this combo will make? Thanks.Sorry no E85 available in Canada,yet at pumps.Only get (Contains 10% ethanol).Also would have to change carb, fuel line,and use all anodized fittings,etc.Little to much hassel at this time.Very good article on E85 in Oct/2011 issue. E85 versus 112 gas.If I,m not mistaken,can,t run ethanol with stripped blower? Needs to be just rotors for more clearance.Please correct me if I,m wrong.Thanks
