E85 in Leaded Engine

[Nick]

I have a 1966 ford 289 that runs on leaded gasoline, If I buy a E85 carburetor can the engine run Like normal (Excluding the MPG) off of straight E85, or would I still half to add a lead additive when I fill up?

I would say you still need the lead or some for of upper cylinder lubricant.
