Yeah, most guys don't know any better. :lol: :lol: :lol: Just kidding, I have run methanol since I started and never messed with racing gas.

Gas, what's Gas :?: That's what i put in my lawn mower, ATV and tow vehicle. Alcohol is what i've ran for yrs. and cost about $2.00 a gal. added the extra burn of 1.66% over gas that's still less than $4.00 a gal, VS $10.00/$12.00 racing gas, and when you tear down for a re-up the pistons and most parts still look brand new. Except for the blower motor :oops:

Zip.

Everyone does things different ;but this will get you close :wink: That's why we are competitors :lol: :lol: :lol:

ill be running race gas.114 most likely..

really alc.is that much cheaper..what all do i have to do to change over?

You have to change to an alcohol carb, have a fuel pump that can be used with alcohol and possibably a larger fuel line from the tank/fuel cell.

Remove the foam from your fuel cell if it has any.

Ding, Ding, Ding.... We have a winner. On race gas in a drag SBC with your combo run 7's. I only run 8's in my 15.5 to 1 SB2 head small block. The only two reasons to run a colder plug would be in a forced induction setup, blower turbo or NOS, or maybe a step colder with methanol. Maybe.

If you have E85 in the area a much better overall choice for fuel, you will need to make sure the fuel system is capable of passing enough fuel and a carb properly modified.

what do you have to do to run e85.i have a place that has it for 2.75 a gallon..
