E85 fuel system

[racinsparky]

Make sure your fuel filter is not paper. The e-85 will eat it up.

How about timing and heat range on plugs from gas? Does that change?

[brad hibbard]

typically timing on e85 is on the high side (35-36)
HOWEVER---stay conservative if dyno testing is not available
several factors go into a total timing number
altitude
fuel curve (based on carb and fuel pressure)
exhaust system
actual "ethanol" content
and always ---is your balancer marked correctly

34 is safe in most cases

we run the same plugs for gas --E85 and alky

great tip from racinsparky on the filter
