plugs for alcohol

Looks like I'm going to be an alcoholic this year.  LOL  Going to have the carb. changed to alcohol and I need to know what to do with spark plugs.  I would think I need to go hotter but if so how much?  Currently running AR3934. Also would the timing need to be changed?

I suspect that the plugs you have should do a good job. Just let the e.t. slip tell you what the timing needs to be.

Thanks Lem. As soon as I know what bearings I need I will call with an order.

I run ngk 8 or9.my experiences with timing have been less went faster.you'll just have to see what it takes. My 526 ran best @26*.the 605 likes a bit more.

what heads do you have?
ignition system?
compression?
I found that when I closed the gap form 35 to 20 it seemed to do better but I have the msd7531 with the HVC coil & 16v system.
the plugs you have should be fine though .

Ported A429 heads by Uncle Charlie, 14/1 compression, 7al3 ignition.

well the ignition is plenty hot enough to go a step or two colder but The ones you are using now will be ok.
what do you gap them @ now?

I gap them at .035 now but I will play with it.
