Fuel efficiency.

[TheBussman]

I had a question relating to this: What mods could be made to this engine to make it more robust & suited for ethanol-supplemented fuels? replacing the flexible fuel lines are the obvious step one, thinking more along the lines of taking advantage of some of the good things about ethanol additives that are known risk factors on the 2F engine. As far as I understand ethanol supplemented fuels run better at higher compression ratios than standard gas, are protective against knocking and detonation, and have better engine cooling properties from the ethanol. My 60 has almost 340k on it and I'm noticing a miss that I am fairly certain comes from worn cam lobes so I've been throwing around rebuilding the engine (vs. driving another 100k on it, which I can also do). wondering what other changes would make sense if running ethanol fuels was an objective

i wouldn't be that worried, but to answer your question: you can replace all the fuel hoses, pump, injectors with e85 rated parts and use a standalone ECU with wideband o2 sensor. if your going to rebuild the motor getting some more compression out of it is worth it i think.



Sorry, this was for the 62 crowd, just noticed your 60. with the carb I think the fuel cutoff is your best bet and run it out of fuel when your not using it. not much else you can do, corrosion is worse with e15, if your jetted perfectly for e10 in theory you would want a tiny bit larger jet for e15, or a carb cheater... the e15 will evaporate out of the carb sooner on e15 and leave you with longer cold crank times to fill up the carb.
