How much boost have you ran with autolite 104 and alky. I ran a 3933 but they fouled quickly. I was thinking of going to autolite 103. My plan is run about 30 #s of boost with alky, need a plug suggestion. I am running a gn1 aluminum head. Thanks
 
If your a autolite guy why not try the 3934?

For me I run NGK, i was running autolites. depending on the season I change plugs but try a NGK R5671A-8
