Witch spark plugs for alky carb??

[SPEEDNEEDS1]

I normally run a AR3933 on gas. I am new to the alky stuff and was just currious what everyone else is running with a carb and alky..... It is a APD 1150 going on a 540 in a dragster if that helps any.

Thanks, I would have been lost with the 3933.

I run both autolite and NGK, but like David says you really have to index the Autolites, because of the longer tip.

JMO

Zip.
